REGISTER MEMORY MAP ADDRESSING
The register map address consists of the following:
• cPCI/PCIe BAR or Base Address for the Board • Module Slot Base Address • Function Offset Address
Board Base Address
The table below lists the BAR used for access to the motherboard and module registers. The second BAR is used internally for motherboard and module firmware updates. The other cPCI/PCIe BARs not listed are not used.
| NAI Boards | Device ID | Bus | Motherboard and Module Register Access | Motherboard and Module Firmware Updates |
| Slave Boards | ||||
| 79G5 | 0x7981 | PCIe | BAR 1 Size: Module Dependent (minimum 64K Bytes) | BAR 2 Size: 1M Bytes |
Module Slot and Function Addresses
The memory map for the modules are dependent on the types of modules on the board and the order in which the modules are installed on the board as well as the firmware installed on the motherboard. The function modules are enumerated allowing for dynamic memory space allocation and therefore the “start” address of the module function register area is factory pre-defined (and read from) the Module Address register. Refer to Figure 1 for an example.
Figure 1. Register Memory Map Addressing for Motherboards with 3 Modules
Address Calculation
Motherboard Registers
Read/Write access to the motherboard registers starts with the base address for the board and then the motherboard base offset address.
For example, to address Module Slot 1 Start Address register (i.e. register address = 0x0400):
- Start with the base address for the board.
- Add the motherboard register address offset.
| Motherboard Address = | Base Address Motherboard Address Offset | = 0x0000 0400 |
| 0x0000 0000 + 0x0400 |
Module Registers:
Read/Write access to the Function module’s registers start with the base address of the board. Add the “content” for the Module Start Address and then, add the specific module function register offset.
For example, to address an appropriate/specific function module with a register offset:
- Start with the base address for the board.
- Add the value (contents) from the module base address offset register (contents/value of Motherboard Memory register for Module 1 (i.e., @ 0x0400) = 0x4000.
- Then add the specific module function Register Offset of interest (i.e., A/D Reading Ch 1 @ 0x1000)
| (Function Specific) Address = | Base Address + | Module Base Address Offset + | Function Register Offset | = 0x0000 5000 |
| 0x0000 0000 | 0x4000 | 0x1000 |

For other operating systems, refer to the naibrd Software Support Kit (SSK) naibsp_system_Monitor_Temperature_Get() routine to manually retrieve the temperature (NOTE: this feature is typically utilized for development/factory use only; contact the factory for additional details on potential use, if required).
Motherboard Sensor Summary Alarm Function: The corresponding sensor bit is set if the sensor has crossed any of its thresholds. Type: unsigned binary word (32-bits) Data Range: See table below Read/Write: R Initialized Value: 0 Operational Settings: This register provides a summary for motherboard sensors. When the corresponding sensor bit is set, the Sensor Threshold Status register for that sensor will indicate the threshold condition that triggered the event. Link to original

Motherboard Sensor Registers
The registers listed in this section apply to each module sensor listed for the Motherboard Sensor Summary Status register. Each individual sensor register provides a group of registers for monitoring motherboard 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 Zynq Core Temperature sensor as an example.

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).
Interrupt Vector Function: Set an identifier for the interrupt. Type: unsigned binary word (32-bit) Data Range: 0x0000 0000 to 0xFFFF FFFF Read/Write: R/W Initialized Value: 0 Operational Settings: When an interrupt occurs, this value is reported as part of the interrupt mechanism.

Type: unsigned binary word (32-bit) Data Range: 0x0000 0000 to 0xFFFF FFFF Read/Write: R/W Operational Settings: The Module Control Commands registers provide the ability to request individual Modules to perform one of the following functions - Reset, Power-down, Power-up. Only one command can be requested at a time per Module. For example, one can't request a Reset and a Power-down at the same time for the same Module. Once the command is recognized and handled, the bit will be cleared. Note
Clearing of the command request bit only indicates the command has been recognized and initiated, it does not indicate that the command action has been completed.
There is one Control Command Request register per Module. Each register is Bit-mapped as shown in the table below:

Note
Actual “as shipped” card Ethernet default IP addresses may vary based upon final ATP configuration(s).
The NAI interface supports IPv4 and IPv6 and both the TCP and UDP protocols. The Ethernet Operation Mode Command Listener application running on the motherboard host processor implements the operation interface. The listener is operational on startup through the nai_MBStartup process and listen on specific ports for commands to process. The default ports are listed below:
- TCP1 - Port 52801
- TCP2 - Port 52802
- UDP1 - Port 52801
- UDP2 - Port 52802
While the listener is active, note that interrupts from the motherboard do not trigger. The listener can be disabled by turning off the nai_MBStartup process through the Motherboard EEPROM. To turn off nai_MBStartup use the command mbeeprom_util set MBStartupInitOnlyFlag 1 in the console, either by serial port or telnet to the motherboard, and then reboot the system. To turn on the nai_MBStartup use the command mbeeprom_util set MBStartupInitOnlyFlag 0 in the console, either by serial port or telnet to the motherboard, and then reboot the system.

The interface uses a specific message framework for all commands and responses. All messages begin with a Preamble code and end with a Postamble code. The message framework is shown below.
Preamble
2 bytes Always
0xD30FSequenceNo
2 bytesType Code
2 byteMessage Length
(2 bytes)Payload
(0..1414 bytes)Postamble
2 bytes
Always
0xF03DMessage Elements
Preamble The Preamble is used to delineate the beginning of a message frame.
The Preamble is always 0xD30F.SequenceNo The SequenceNo is used to associate Commands with Responses. Type Code Type Codes are used to define the type of Command or Response the message contains. Message Length The Message Length is the number of bytes in the complete message frame starting with and including the
Preamble and ending with and including the Postamble.Payload The Payload contains the unique data that makes up the command or response.
Payloads vary based on command type.Postamble The Postamble is use to delineate the end of a message frame.
The Postamble is always 0xF03D.Notes
- The messaging protocol applies only to card products.
- Messaging is managed by the connected (client) computer. The client computer will send a single message and wait for a reply from the card. Multiple cards may be managed from a single computer, subject to channel and computer capacity.
Board Addressing
The interface provides two main addressing areas: Onboard and Off-board.
Onboard addressing refers to accessing resources located on the board that is implementing the operation interface (including its modules).
Off-board addressing refers to accessing resources located on another board reachable via VME, PCI, or other bus. Off-board addressing requires a Master/Slave configuration.
The user must always specify if a particular address is Onboard or Off-board. See the command descriptions for the onboard and off-board flags.
Within a particular board (Onboard or Off-board), the address space is broken up into two areas: Motherboard Common Address Space and Module Address Space. All addresses are 32-bit.
Motherboard Common Address Space starts at 0x00000000 and ends at 0x00004000. This is a 4Kx32-bit address space (16 kbytes).
Module Address Space starts at 0x00004000. Module addressing is dynamically configured at startup. NAI boards support between 1 and 6 modules. The minimum module address space size is 4Kx32 (16 kbytes) and module sizes are always a multiple of 4Kx32.
Module addressing is dynamic and cumulative. The first detected module (starting with Slot 1) is given an address of 0x00004000. The 2nd detected Module is given an address of:
First_Detected_Module_Address + First_Detected_Module_Size
Note
Slots do not define addresses.
If no module is detected in a module slot, that slot is not given an address. Therefore, if the first detected Module is in Slot 2, then that module address will be 0x00004000. If the next detected module is in Slot 4, then the address of that Module will be:
Second_Detected_Module_Address = First_Detected_Module_Address + First_Detected_Module_Size
If a 3rd Module is detected in Slot 6, then the address of that Module will be:
Third_Detected_Module_Address = Second_Detected_Module_Address + Second_Detected_Module_Size
Note
Module addresses are calculated at each board startup when the modules are detected. Therefore, if a module should fail to be detected due to malfunction or because it was removed from the motherboard, the addresses of the modules that follow it in the slot sequence will be altered. This is important to note when programming to this interface.
Users can always retrieve the Module Addresses, Module Sizes and Module IDs from the fixed Motherboard Common address area. This data is set upon each board startup. While the Module Addressing is dynamic, the address where these addresses are stored is fixed. For example, to find the startup address of the module location in Slot 3, refer to the MB Common Address 0x00000408 from the Motherboard Common Addresses table that follows.

|---|---|
| 2. Discrete I/O Module (DT1) | All GND pins are common within the module, but, isolated from system/power GND. Each pin should be individually wired for optimal power current distribution. |
| 3. TTL I/O Module (TL1) | I/O referenced to system power GND. |
| 4. CMRP - A/D Module(s) (ADx) | 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 CMRP, which is isolated from system/power GND. |
