ADE-ADF Overview

NAI’s Analog-to-Digital modules ADE,and ADF are high-performance smart function modules designed for use in military, industrial, and commercial applications. These modules feature 16 channels with up to 16-bit Successive Approximation Register (SAR) A/D converters, simultaneous sampling. The maximum programmable, expected full-scale range input for the modules is ±10V (ADE), and ±100V (ADF), respectively.

The A/D converters have programmable sample rates of up to 200 kHz. The input range and gain are also field-programmable for each channel, with the ability to set lower expected, full-scale voltage gain ranges to assure the use of full resolution. Each channel includes a fixed, second-order, anti-aliasing filter and a digital post filter with a programmable breakpoint that enables users to field-adjust the filtering for each channel.

The extended A/D FIFO buffering capabilities of these modules support greater storage/management of the incoming signal samples (data) for post-processing applications. Data samples can be stored in the buffer either at the maximum programmed base A/D sample rate or by an integer-divided sample rate, with programmable FIFO buffer thresholds maximizing data flow control (movement in and out of the FIFO). Incremental relative time-stamping between samples is also provided as a programmable option.

All A/D channels are self-aligning and continuous Background Built-in-Test (BIT) status is provided for channel health and operation feedback. On a rotating basis, each channel is automatically trimmed/tested for optimal conversion and reliability to eliminate offset and gain errors throughout the entire operating envelope (temperature and drift control). Open inputs are sensed and flagged, making these smart function modules an ideal choice for precise and reliable data acquisition and signal processing in a wide range of applications.

PRINCIPLE OF OPERATION

Analog-to-Digital modules ADE and ADF are 16-Channel A/D modules that feature independent 16-bit Successive Approximation Register (SAR) A/Ds.

5.0 V50 V

1.25 V12.5 V
0.625 V6.25 V

*Programmable, per channel, as Full Scale (FS) range inputs, where range is -FS to +FS or 0 to FS VDC. The ability to set lower voltages for FS assures the utilization of the maximum resolution.

The module(s) provide true simultaneous sampling A/D converters for all 16 channels with programmable full-scale range inputs. The A/D converters have programmable sample rates of up to 200 kHz. Additional features include FIFO sample data storage with trigger/capture options, IIR filtering, open-line and over-voltage detection. Additional BIT capabilities include front end differential-amplifier malfunction detection (ADF). Taking advantage of the fast and simultaneous sampling SAR A/D architecture, the module provides an effective A/D interface for applications requiring control loop integration and parallel data acquisition.

Built-In Test (BIT)/Diagnostic Capability

The AD module supports three types of built-in tests: Power-On, Continuous Background and Initiated. The results of these tests are logically OR’d together and stored in the BIT Dynamic Status and BIT Latched Status registers.

In addition to BIT, the AD module tests for loss of +12V and -12V power, and inter-FPGA data transfer errors between the Lattice FPGA and Xilinx FPGA. On the ADE module, the module tests for Open/Over-voltage conditions on the positive and negative connections. On the ADF module, the module continually tests the channel’s Front-end Amplifier to ensure it is working properly.

Power-On Self-Test (POST)/Power-On BIT (PBIT)/Start-Up BIT (SBIT)

the PBIT test definition is defined at the Initiated BIT (IBIT). This is automatically performed on power-up, with the results posted. The power-on self-test is performed on each channel automatically when power is applied and report the results in the BIT Status register when complete. After power-on, the Power-on BIT Complete register should be checked to ensure that POST/PBIT/SBIT test is complete before reading the BIT Dynamic Status and BIT Latched Status registers.

Continuous Background Built-In Test

The background Built-In-Test or Continuous BIT (CBIT) (“D2”) runs in the background where each channel is checked to a test accuracy of 0.2% FS. The testing is totally transparent to the user, requires no external programming, and has no effect on the operation of the module or card. For the ADE module, all channels are monitored for open input during the CBIT test. The technique used by the CBIT test consists of an “add-2, subtract-1” counting scheme. The BIT counter is incremented by 2 when a BIT-fault is detected and decremented by 1 when there is no BIT fault detected and the BIT counter is greater than 0. When the BIT counter exceeds the (programmed) Background BIT Threshold value, the specific channel’s fault bit in the BIT status register will be set. Note, the interval at which BIT is performed is dependent and differs between module types. Rater than specifying the BIT Threshold as a “count”, the BIT Threshold is specified as a time in milliseconds. The module will convert the time specified to the BIT Threshold “count” based on the BIT interval for that module. The “add-2, subtract-1” counting scheme effectively filters momentary or intermittent anomalies by allowing them to “come and go“ before a BIT fault status or indication is flagged. This prevents spurious faults from registering valid such as those caused by EMI and/or dirty power causing false BIT faults. Putting more “weight” on errors (“add-2”) and less “weight” on subsequent passing results (subtract-1) will result in a BIT failure indication even if a channel “oscillates” between a pass and fail state.

Initiated Built-In Test

The AD module supports two off-line Initiated Built-in Test, User Initiated BIT (UBIT) (“D0”) and Initiated BIT (IBIT) (“D3”).

UBIT test is used to check the card and interface. This test disconnects all A/D channels from the I/O and connects them across an internal D/A. Test voltage is controlled by the user by setting the desired voltage in the UBIT Test Data register. External reference voltage is not required. While UBIT test is enabled, the A/D Reading register will reflect the value entered for the test voltage. Note the units of the A/D Reading may represent voltage, current or engineering units depending on the mode specified by setting the Enable Floating Point Mode register.

IBIT test starts an initiated BIT test that disconnects all A/D’s from the I/O and then connects them across an internal stimulus. Each channel will be checked to a test accuracy of 0.2% FS and monitored for open inputs. The IBIT test cycle is completed within 20 seconds (depending on the sample rate) and results can be read from the BIT Status registers after the IBIT bit changes from 1 to 0 indicating that the IBIT test is complete. The test can be enabled or disabled at any time by writing to the appropriate register.

A/D FIFO Buffering

The Analog-to-Digital modules include A/D FIFO Buffering for greater control of the incoming signal (data) for analysis and display. When initialized and triggered, the A/D buffer will accept/store the data based on the same Sample Rate register combined with the number of active channels, or at a lower rate when utilizing the FIFO Skip Count feature. Programmable buffer sample thresholds can be utilized for data flow control.

Threshold and Saturation Programming

The Analog-to-Digital Modules provide registers that support threshold and saturation detection. Refer to “Analog-to-Digital Threshold and Saturation Programming Module Manual” for the Principle of Operation description.

Status and Interrupts

The Analog-to-Digital Modules provide registers that indicate faults or events. Refer to “Status and Interrupts Module Manual” for the Principle of Operation description.

Module Common Registers

The Analog-to-Digital Modules include module common registers that provide access to module-level bare metal/FPGA revisions & compile times, unique serial number information, and temperature/voltage/current monitoring. Refer to “Module Common Registers Module Manual” for the detailed information.

Engineering Scaling Conversions

The A/D Module Threshold, Saturation and Measurement registers can be programmed to be utilized as single precision floating point values (IEEE-754) or as 32-bit integer values.

It is very often necessary to convert a voltage or current reading into a more useful value such as PSI (Pounds per Square Inch), GPM (Gallons per Minute), LBS (pounds), etc. For example, when measuring force, it would be more beneficial to read the data as LBS (pounds) instead of volts. Other examples would be reading the data as PSI for pressure or GPM for flow. When the Enable Floating Point Mode register is set to 1, the values entered for the Floating Point Scale register and Floating Point Offset register will be used to convert the current or voltage measurement (i.e., A/D Reading and FIFO Buffer Data registers) to the associated engineering unit as follows:

AD Data in Engineering Units (Floating Point) =
                    (AD Value (Volts/Current) * Floating Point Scale) + Floating Point Offset

The purpose for providing this feature is to offload the processing that is normally performed by the mission processor to convert the integer values to engineering unit values.

When the Enable Floating Point Mode register is set to 1 (Floating Point Mode) the following registers are formatted as Single Precision Floating Point Value (IEEE-754):

  • A/D Reading
  • FIFO Buffer Data
  • Threshold Detect Level*
  • Upper and Lower Saturation*

*When the Enable Floating Point Mode register is set to 1, it is important that these registers are updated with the Single Precision Floating Point (IEEE-754) representation of the value for proper operation of the channel. Conversely, when the Enable Floating Point Mode register is set to 0, these registers must be updated with the Integer 32-bit representation of the value.

Note

when changing the Enable Floating Point Mode from Integer Mode to Floating Point Mode or vice versa, the following steps are followed to avoid faults from falsely being generated:

  1. Set the Enable Floating Point Mode register to the desired mode (Integer or Floating Point).
  2. The application waits for the Floating Point State register to match the value for the requested Floating Point Mode (Integer = 0, Floating Point = 1); this indicates that the module’s conversion of the register values and internal values is complete. Data registers will be converted to the units specified and can be read in that specified format.

REGISTER DESCRIPTIONS

The register descriptions provide the register name, Type, Data Range, Read or Write information, Initialized Value, a description of the function and, in most cases, a data table.

A/D Measurement Registers

The A/D readings are normally in terms of voltage or current. When the Enable Floating Point Mode is enabled, the register value formatted as Single Precision Floating Point Value (IEEE-754), in addition the Floating Point Scale and Floating Point Offset will be applied to convert the voltage or current to engineering units.

FIFO Thresholds

The FIFO Almost Empty, FIFO Low Watermark, FIFO High Watermark, FIFO Almost Full and FIFO Buffer Size sets the threshold limits that are used to set the bits in the FIFO Status register.

FIFO Almost Empty
Function:The FIFO Almost Empty is used to set the limits for the “almost empty” status.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x000F FFFF
Read/Write:R/W
Initialized Value:Not set
Operational Settings:When the Words in FIFO counter is greater than or equal to the value stored in the FIFO Almost Empty register, the “almost empty” bit (D1) of the FIFO Status register will be set. When the Words in FIFO counter is less than the value stored in the register, the “almost empty” bit (D1) of the FIFO Status register will be reset.

Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x000F FFFF
Read/Write:R/W
Initialized Value:Not set
Operational Settings:When the Words in FIFO counter is less than or equal to the value stored in the FIFO Low Watermark register, the “low watermark” bit (D2) of the FIFO Status register will be set. When the Words in FIFO counter is greater than the value stored in the register, the “low watermark” bit (D2) of the FIFO Status register will be reset.

Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x000F FFFF
Read/Write:R/W
Initialized Value:Not set
Operational Settings:When the Words in FIFO counter is greater than or equal to the value stored in the FIFO High Watermark register, the “high watermark” bit (D3) of the FIFO Status register will be set. When the Words in FIFO counter is less than the value stored in the high-threshold, the “high watermark” bit (D3) of the FIFO Status register will be reset.
FIFO Almost Full
Function:The FIFO Almost Full is used to set the limits for the “almost full” status.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x000F FFFF
Read/Write:R/W
Initialized Value:Not set
Operational Settings:When the Words in FIFO counter is greater than or equal to the value stored in the FIFO Almost Full register, the “almost full” bit (D4) of the FIFO Status register will be set. When the Words in FIFO counter is less than the value stored in the register, the “almost full” bit (D4) of the FIFO Status register will be reset.
FIFO Buffer Size
Function:Sets the number of samples to be taken and placed into the FIFO when a trigger occurs.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x000F FFFF
Read/Write:R/W
Initialized Value:0x000F FFFF
Operational Settings:The size of each sample (number of words written to the FIFO per sample) is determined by the sample format described by the FIFO Buffer Control register. When the Words in FIFO counter reaches the FIFO Buffer Size, the “sample done” bit (D6) is set and no additional samples will be placed in the FIFO. When Words in FIFO counter is less than FIFO Buffer Size, the “sample done” bit (D6) will be reset.
Data Control
Function:Sets the format of the samples to be stored in the FIFO buffer which is determined by the bitmapped table.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x0000 0014
Read/Write:R/W
Initialized Value:0
Operational Settings:The Time Stamp data format (D4) requires one word of storage space from the FIFO buffer. For example, if (D4) is set to 0 and the FIFO Buffer Size register is set to 1, a FIFO write will put one word of data in the FIFO memory space per sample and discard the timestamp (sample counter). Since the maximum physical size of FIFO is 1M words for each channel, the value in the FIFO Buffer Size and Data Control registers could cause an overflow to the FIFO buffer. When an overflow condition occurs, any data that is not placed in the FIFO will be lost.

Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0xFFFF FFFF
Read/Write:R/W
Initialized Value:0 (No Skip Count (FIFO stores every sample))
Operational Settings:If the sample rate for a channel is 10 kHz, there would be a new sample every 100μs. By setting the FIFO skip count to 1, the FIFO will store a new sample every 200 μs, or at a 5 kHz rate.
Clear FIFO
Function:Clears FIFO by resetting the Words in FIFO count.
Type:unsigned binary word (32-bit)
Data Range:0 or 1
Read/Write:W
Initialized Value:N/A

Background BIT Threshold Programming Registers

The Background BIT Threshold register provides the ability to specify the minimum time before the BIT fault is reported in the BIT Status registers. The BIT Count Clear register provides the ability to reset the BIT counter used in CBIT.

Background BIT Threshold
Function:Sets BIT Threshold value (in milliseconds) to use for all channels for BIT failure indication.
Type:unsigned binary word (32-bit)
Data Range:1 ms to 65 seconds
Read/Write:R/W
Initialized Value:5 ms
Operational Settings:The interval at which BIT is performed is dependent and differs between module types. Rather than specifying the BIT Threshold as a “count”, the BIT Threshold is specified as a time in milliseconds. The module will convert the time specified to the BIT Threshold “count” based on the BIT interval for that module.
BIT Count Clear
Function:Resets the CBIT internal circuitry and count mechanism. Set the bit corresponding to the channel you want to clear.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x0000 FFFF
Read/Write:W
Initialized Value:0
Operational Settings:Set bit to 1 for channel to resets the CBIT mechanisms. Bit is self-clearing.

Module Common Registers

Refer to “Module Common Registers Module Manual” for the register descriptions.

Status and Interrupt Registers

The AD modules provide status registers for BIT, FIFO, Overcurrent, Open, External Power Loss, Threshold Detect, Saturation, Inter-FPGA Failure and Summary.

Channel Status Enable
Function:Determines whether to update the status for the channels. This feature can be used to “mask” status bits of unused channels in status registers that are bitmapped by channel.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0x0000 FFFF (Channel Status)
Read/Write:R/W
Initialized Value:0x0000 FFFF
Operational Settings:When the bit corresponding to a given channel in the Channel Status Enable register is not enabled (0) the status will be masked and report “0” or “no failure”. This applies to all statuses that are bitmapped by channel (BIT Status, Overcurrent Status, Front-end Amplifier Failure Status and Summary Status).

Note

Background BIT will continue to run even if the Channel Status Enable is set to 0.

  • Power-on BIT Error (Dynamic and Latched)
  • Anti-Aliasing Filter Error (Dynamic and Latched)
  • Voltage Reading Accuracy Error (Dynamic and Latched)

The diagnostic Dynamic register indicates the current condition of the channel’s BIT error status. The diagnostic Latched Status register will maintain the last condition of the channel’s BIT error status. The diagnostic Latched Status will be cleared when the BIT Latched Status register is cleared.

Open/Over-Voltage Status

There are four registers associated with the Open/Over-Voltage Status: Dynamic, Latched, Interrupt Enable, and Set Edge/Level Interrupt. These registers are only applicable to Module ADE.

Note

the channel 16 negative pin on the I/O connector MUST be tied to ground for the open detection circuitry to function properly. Failure to connect the channel 16 negative pin to ground will cause intermittent open-detect behavior on all channels.

Note

both ends of any unused channels (Pos/Neg) should be tied to the channel 16 negative pin, referred to as the Common Mode Reference Point (CMRP; isolated from system power/ground). Tying only one end of a channel, while leaving the opposing end open, may cause Open Circuit Detection to deliver unwanted voltages to your channels in use.

Open/Over-Voltage Status
Function:Sets the corresponding bit associated with the channel's Open/Over-Voltage error.

Inter-FPGA Failure Status

Data is periodically transferred between the Lattice FPGA and the Xilinx FPGA. A CRC value is calculated and verified with each data transfer. A CRC error flag is sent from the Lattice FPGA to the Xilinx FPGA if a CRC error is detected. The Xilinx FPGA contains a counter that will increase by two when a CRC error is flagged and decremented by one when there is no CRC error. If the counter reaches ten, the Xilinx FPGA will set the Inter-FPGA Failure status bit and shut down the isolated power supply. In order to recover from an Inter-FPGA Failure, the module needs to be reset and re-initialized.

There are four registers associated with the Inter-FPGA Status: Dynamic, Latched, Interrupt Enable, and Set Edge/Level Interrupt. 0 = Normal; 0x0FFF = Inter-FPGA Communication Failure. The status represents the status for all channels on the module.

Interrupt Vector and Steering

When interrupts are enabled, the interrupt vector associated with the specific interrupt can be programmed (typically with a unique number/identifier) such that it can be utilized in the Interrupt Service Routine (ISR) to identify the type of interrupt. When an interrupt occurs, the contents of the Interrupt Vector registers is reported as part of the interrupt mechanism.

In addition to specifying the interrupt vector, the interrupt can be directed (“steered”) to the native bus or to the application running on the onboard ARM processor.

Note

the Interrupt Vector and Interrupt Steering registers are mapped to the Motherboard Common Memory and these registers are associated with the Module Slot position (refer to Function Register Map).

STATUS REGISTERS
*When an event is detected, the bit associated with the event is set in this register and will remain set until the user clears the event bit. Clearing the bit requires writing a 1 back to the specific bit that was set when read (i.e., write-1-to-clear, writing a “1” to a bit set to “1” will set the bit to “0).

APPENDIX A: INTEGER/FLOATING POINT MODE PROGRAMMING

Integer Mode Programming

When in Integer Mode, the values in the following registers are dependent on the Polarity and Range settings:

  • A/D Reading and FIFO Buffer Data
  • UBIT Test Data
  • Threshold Level and Threshold Hysteresis
  • Low and High Saturation

A/D Reading and FIFO Buffer Data

The LSB for the 16-bit word resolution for the A/D Reading register and the FIFO Buffer Data register is dependent on the Polarity and Range setting. The 32-bit binary value in these registers use the two’s complement form to represent the positive and negative values.

For example:

ADE Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 10.0 V)

    LSB = 10.0 / 0x0000 7FFF = 10.0 / 2<sup>15</sup> = **10.0 / 32768**
    
    If the register value is 14745 (binary equivalent for this value is **0x0000 3999**), conversion to the voltage value is 14745 * (10.0 / 32768) = **4.50 V**.
    
    If the register value is -100 (binary equivalent for this value is **0xFFFF FF9C**), conversion to the voltage value is -100 * (10.0 / 32768) = **-0.0305 V**.
    
  • Polarity & Range Register = 0x00 (Polarity = Unipolar & Range = 10.0 V)

    LSB = 10.0 / 0x0000 FFFF = 10.0 / 2<sup>16</sup> = **10.0 / 65536**
    

If the register value is 14745 (binary equivalent for this value is 0x0000 3999), conversion to the voltage value is 14745 * (10.0 / 65536) = 2.25 V.

ADF Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 100.0 V)

    LSB = 100.0 / 0x0000 7FFF = 100.0 / 2<sup>15</sup> = **100.0 / 32768**
    
    If the register value is 14745 (binary equivalent for this value is **0x0000 3999**), conversion to the voltage value is 14745 * (100.0 / 32768) = **45.0 V**.
    
    If the register value is -100 (binary equivalent for this value is **0xFFFF FF9C**), conversion to the voltage value is -100 * (100.0 / 32768) = **-0.305 V**.
    
  • Polarity & Range Register = 0x00 (Polarity = Unipolar & Range = 100.0 V)

    LSB = 100.0 / 0x0000 FFFF = 100.0 / 2<sup>16</sup> = **100.0 / 65536**
    

If the register value is 14745 (binary equivalent for this value is 0x0000 3999), conversion to the voltage value is 14745 * (100.0 / 65536) = 22.5 V.

UBIT Test Programming

The value to set in the UBIT Test Data register is dependent on the Polarity and Range setting. In the Integer mode, the A/D Reading register will represent the voltage (ADE, ADF) measured as the result of setting the UBIT test value.

For example:

ADE Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 10.0 V)

    LSB = 10.0 / 0x0000 7FFF = 10.0 / 2<sup>15</sup> = **10.0 / 32768**

ADF Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 100.0 V ) LSB = 100.0 / 0x0000 7FFF = 100.0 / 215 = 100.0 / 32768

Threshold Programming

The LSB for the 16-bit word resolution for the Threshold Detect Level and Threshold Detect Hysteresis registers is dependent on the Polarity and Range setting. The 32-bit binary value in these registers use the two’s complement form to represent the positive and negative values.

For example:

ADE Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 10.0 V)

    LSB = 10.0 / 0x0000 7FFF = 10.0 / 2<sup>15</sup> = **10.0 / 32768**

  • Polarity & Range Register = 0x00 (Polarity = Unipolar & Range = 10.0 V)

Saturation Programming

The LSB for the 16-bit word resolution for the Low and High Saturation registers is dependent on the Polarity and Range setting. The 32-bit binary value in these registers use the two’s complement form to represent the positive and negative values.

For example:

ADE Modules:

Floating Point Mode Voltage/Current Programming

When in Floating Point Mode, the registers listed in the Integer Mode Programming section are still dependent on the Polarity and Range settings, however, the module handles the conversion of the 32-bit binary value to Single Precision Floating Point Value (IEEE-754) format. The values in the Floating Point Scale register and Floating Point Offset register are used in the conversion. For results to represent voltage (ADE, ADF modules):

  • Set Floating Point Scale register to Range
  • Set Floating Point Offset register to 0

A/D Reading and FIFO Buffer Data

For example:

ADE Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 10.0 V)

    Floating Point Scale = **10.0** = **10.0 V**
    
    Floating Point Offset = **0**

14745 / 32768 = 0.45 (0x0000 3999/0x0000 7FFF)(0.45 * 10.0) + 0.0 = 4.500x4090 0000
-100 / 32768 = -0.00305 (0xFFFF FF9C/0x0000 7FFF)(-0.00305 * 10.0) + 0.0 = -0.03050xBCF9 DB23
  • Polarity & Range Register = 0x00 (Polarity = Unipolar & Range = 10.0 V)

    Floating Point Scale = **10.0** = **10.0 V**
    
    Floating Point Offset = **0**

UBIT Test Programming

The value to set in the UBIT Test Data register is dependent on the Polarity and Range settings and these settings will determine the 32-bit value to set in this register. In the Floating Point mode, the A/D Reading register will represent the voltage measured as the result of setting the UBIT test value.

For example:

ADE Modules:

  • Polarity & Range Register = 0x10 (Polarity = Bipolar & Range = 10.0 V)

    LSB = 10.0 / 0x0000 7FFF = 10.0 / 2<sup>15</sup> = **10.0 / 32768**

Floating Point Mode Engineering Units Programming

When in Floating Point Mode, the registers listed in the Integer Mode Programming section are still dependent on the Polarity and Range settings, however, the module handles the conversion of the 32-bit binary value to Single Precision Floating Point Value (IEEE 754) format. The values in the Floating Point Scale register and Floating Point Offset register are used in the conversion. For results to be represent engineering units:

  • Set Floating Point Scale register to *Range ** Engineering Unit Conversion
  • Set Floating Point Offset register to Engineering Unit Conversion Bias

A/D Readings

The following calculation is used to convert A/D Reading to engineering units:

        AD Data in Engineering Units (Floating Point) =

              (AD Value (Volts/Current) * **Floating Point Scale**) + **Floating Point Offset**

For example:

ADE Modules:

  • A signal of -10V to 10V indicate a displacement from -38.5mm to 38.5 mm respectively.

    Polarity & Range Register = **0x10** (Polarity = **Bipolar** & Range = **10.0 V**)

Notes

(CMRP)The Common Mode Reference Point (CMRP) is an isolated reference connection for all the A/D channels. For expected high common mode voltage applications, it is
recommended that the pin designated as CMRP be referenced (direct or resistor coupled) to the signal source GND reference (must have current path between CMRP and signal
source generator) to minimize common mode voltage within the acceptable specification range. All channels within the module are independent but share a common CMRP, which
is isolated from system/power GND.

STATUS AND INTERRUPTS

Status registers indicate the detection of faults or events. The status registers can be channel bit-mapped or event bit-mapped. An example of a channel bit-mapped register is the BIT status register, and an example of an event bit-mapped register is the FIFO status register.

For those status registers that allow interrupts to be generated upon the detection of the fault or the event, there are four registers associated with each status: Dynamic, Latched, Interrupt Enabled, and Set Edge/Level Interrupt.

Dynamic Status: The Dynamic Status register indicates the current condition of the fault or the event. If the fault or the event is momentary, the contents in this register will be clear when the fault or the event goes away. The Dynamic Status register can be polled, however, if the fault or the event is sporadic, it is possible for the indication of the fault or the event to be missed.

Latched Status: The Latched Status register indicates whether the fault or the event has occurred and keeps the state until it is cleared by the user. Reading the Latched Status register is a better alternative to polling the Dynamic Status register because the contents of this register will not clear until the user commands to clear the specific bit(s) associated with the fault or the event in the Latched Status register. Once the status register has been read, the act of writing a 1 back to the applicable status register to any specific bit (channel/event) location will “clear” the bit (set the bit to 0). When clearing the channel/event bits, it is strongly recommended to write back the same bit pattern as read from the Latched Status register. For example, if the channel bit-mapped Latched Status register contains the value 0x0000 0005, which indicates fault/event detection on channel 1 and 3, write the value 0x0000 0005 to the Latched Status register to clear the fault/event status for channel 1 and 3. Writing a “1” to other channels that are not set (example 0x0000 000F) may result in incorrectly “clearing” incoming faults/events for those channels (example, channel 2 and 4).

Interrupt Enable: If interrupts are preferred upon the detection of a fault or an event, enable the specific channel/event interrupt in the Interrupt Enable register. The bits in Interrupt Enable register map to the same bits in the Latched Status register. When a fault or event occurs, an interrupt will be fired. Subsequent interrupts will not trigger until the application acknowledges the fired interrupt by clearing the associated channel/event bit in the Latched Status register. If the interruptible condition is still persistent after clearing the bit, this may retrigger the interrupt depending on the Edge/Level setting.

Set Edge/Level Interrupt: When interrupts are enabled, the condition on retriggering the interrupt after the Latch Register is “cleared” can be specified as “edge” triggered or “level” triggered. Note, the Edge/Level Trigger also affects how the Latched Register value is adjusted after it is “cleared” (see below).

  • Edge triggered: An interrupt will be retriggered when the Latched Status register change from low (0) to high (1) state. Uses for edge-triggered interrupts would include transition detections (Low-to-High transitions, High-to-Low transitions) or fault detections. After “clearing” an interrupt, another interrupt will not occur until the next transition or the re-occurrence of the fault again.

  • Level triggered: An interrupt will be generated when the Latched Status register remains at the high (1) state. Level-triggered interrupts are used to indicate that something needs attention.

Interrupt Vector and Steering

When interrupts are enabled, the interrupt vector associated with the specific interrupt can be programmed with a unique number/identifier defined by the user such that it can be utilized in the Interrupt Service Routine (ISR) to identify the type of interrupt. When an interrupt occurs, the contents of the Interrupt Vector registers is reported as part of the interrupt mechanism. In addition to specifying the interrupt vector, the interrupt can be directed (“steered”) to the native bus or to the application running on the onboard ARM processor.

Interrupt Trigger Types

In most applications, limiting the number of interrupts generated is preferred as interrupts are costly, thus choosing the correct Edge/Level interrupt trigger to use is important.

Example 1: Fault detection

This example illustrates interrupt considerations when detecting a fault like an “open” on a line. When an “open” is detected, the system will receive an interrupt. If the “open” on the line is persistent and the trigger is set to “edge”, upon “clearing” the interrupt, the system will not regenerate another interrupt. If, instead, the trigger is set to “level”, upon “clearing” the interrupt, the system will re-generate another interrupt. Thus, in this case, it will be better to set the trigger type to “edge”.

Example 2: Threshold detection

This example illustrates interrupt considerations when detecting an event like reaching or exceeding the “high watermark” threshold value. In a communication device, when the number of elements received in the FIFO reaches the high-watermark threshold, an interrupt will be generated. Normally, the application would read the count of the number of elements in the FIFO and read this number of elements from the FIFO. After reading the FIFO data, the application would “clear” the interrupt. If the trigger type is set to “edge”, another interrupt will be generated only if the number of elements in FIFO goes below the “high watermark” after the “clearing” the interrupt and then fills up to reach the “high watermark” threshold value. Since receiving communication data is inherently asynchronous, it is possible that data can continue to fill the FIFO as the application is pulling data off the FIFO. If, at the time the interrupt is “cleared”, the number of elements in the FIFO is at or above the “high watermark”, no interrupts will be generated. In this case, it will be better to set the trigger type to “level”, as the purpose here is to make sure that the FIFO is serviced when the number of elements exceeds the high watermark threshold value. Thus, upon “clearing” the interrupt, if the number of elements in the FIFO is at or above the “high watermark” threshold value, another interrupt will be generated indicating that the FIFO needs to be serviced.

PRINCIPLE OF OPERATION

The AD modules provide the ability to monitor the acquired data and set a status when the specific thresholds are reached.

Threshold Detect

There are two thresholds that can be independently programmed on the A/D modules. These thresholds are used to monitor the acquired data and set a status when the specified thresholds are reached. A configurable hysteresis may also be set to determine when the Threshold Detect registers are cleared. The threshold detection can be configured as a FIFO trigger to capture data based on a specified event. Refer to Figure 1 and Figure 2 for illustrations for Threshold Detect Programming.

Figure 1. Threshold Programming with Hysteresis

Figure 2. Threshold Programming with No Hysteresis

Saturation Programming

A low and high saturation setting that can be independently programmed on the A/D modules. These saturation values are used to monitor the acquired data and set a status when the specified saturation is reached as well as setting the A/D reading to the saturation value. Saturation programming can be used to prevent the A/D reading from exceeding the saturation value. Refer to Figure 3 for illustrations of Saturation Programming

There are four registers associated with the Threshold Detect Status: Dynamic, Latched, Interrupt Enable, and Set Edge/Level Interrupt.

0 = Normal; 1 = Outside of threshold range. The status is created based on the values set in the Threshold Detect 1 and Threshold Detect 2 registers. Bits D0 and D1 represent if channel 1 is outside the threshold for Threshold Detect 1 and Threshold Detect 2 respectively, Bits D2 and D3 represent if channel 2 is outside the threshold for Threshold Detect 1 and Threshold Detect 2 respectively, etc. This pattern continues for all channels.

Function:Sets the corresponding bit associated with the channel’s Threshold Detect error.

Saturation Status

There are four registers associated with the Saturation Status: Dynamic, Latched, Interrupt Enable, and Set Edge/Level Interrupt.

0 = Normal; 1 = Outside of saturation range. The status is created based on the values set in the Low Saturation and High Saturation registers. Bits D0 and D1 represent if channel 1 is outside the voltage for Low Saturation and High Saturation respectively, Bits D2 and D3 represent if channel 2 is outside the voltage for Low Saturation and High Saturation respectively, etc. This pattern continues for all channels.

Function:Sets the corresponding bit associated with the channel’s Saturation error.

FUNCTION REGISTER MAP

Key:

Bold Italic= Configuration/Control
Bold Underline= State/Measurement/Status

*When an event is detected, the bit associated with the event is set in this register and will remain set until the user clears the event bit. Clearing the bit requires writing a 1 back to the specific bit that was set when read (i.e. write-1-to-clear, writing a ‘1’ to a bit set to ‘1’ will set the bit to ‘0’).

**Data is represented in Floating Point if Enable Floating Point Mode register is set to Floating Point Mode (1)

Module Sensor Registers

The registers listed in this section apply to each module sensor listed for the Module Sensor Summary Status register. Each individual sensor register provides a group of registers for monitoring module temperatures readings. From these registers, a user can read the current temperature of the sensor in addition to the minimum and maximum temperature readings since power-up. Upper and lower critical/warning temperature thresholds can be set and monitored from these registers. When a programmed temperature threshold is crossed, the Sensor Threshold Status register will set the corresponding bit for that threshold. The figure below shows the functionality of this group of registers when accessing the Interface Board PCB Temperature sensor as an example.
