Real-Time Clock

Real-Time Clock/Calendar (RTCC) is used to provide a system time and date function or can be used as an event timer. In addition, the MCP79410 includes:

  • 64 Bytes SRAM, Battery Backed

  • 1 Kbits EEPROM (128x8)

  • Power-Fail Time-Stamp for Battery Switchover

To maintain the RTCC and SRAM functions when the 12 V power is off, the RTC_STDBY pin must be connected to an external battery or power supply. The RTC_STDBY supply voltage should be between 1.4 V to 5.0 V. A typical RTC_STDBY supply requirement is 3.0 V @ 5 µA.

CAUTION: 5.5 V is the maximum allowable RTC_STDBY input voltage. Any voltage larger than 5.5 V on the RTC_STDBY pin will damage the RTCC.

Temperature Sensor

The T2080 processor has two pins that are connected to a thermal body diode on the processors die. This diode allows for direct die temperature measurements. The ADT7461 I2C device is used to measure the change in forward bias voltage (VBE) of the body diode. The ADT7461and thermal body diode together allow for direct reading of the die temperature, to an accuracy of ±3°C (does not account for body diode variation).

Device:

On Semi, ADT7461ARMZ

I2C address:

0x4C

The user should refer to the sensor chip datasheet for details on operation. Default temperature limits are set via Uboot (see table below):

When configured, the sensor can generate an interrupt to the T2080 when temperature limits are exceeded (either high or low). This interrupt is connected to the T2080 as IRQ03 (see Hardware Interrupt section). A temperature alarm signal is also routed to the PRC and may be used to generate a shutdown (see Temperature Sensing Registers section).

SPI

Serial Peripheral Interface Bus or SPI is a synchronous serial data link standard. SPI operates in full duplex mode. SPI devices communicate in master/slave mode where the master device starts a frame and sources the clock. The T2080 CPU has one SPI controller with four device select pins (SPI_CS [3:0]). SPI_CS [0] is attached to an FRAM. SPI_CS [1] is attached to a TPM. SPI_C [2,3] are unconnected.

GPIO Data

Function:

Reads the GPIO state of a specific channel’s I/O pin. When configured as an output, write to this register to set the channel to drive high or low. Bitmapped per GPIO channel.

Function Address Offset(s):

0x26

Type:

binary word (16-bit)

Read/Write:

R/W

Initialized Value:

0x0000

Operational Settings:

When GPIO_DIR register has channel configured as an input (0), read corresponding bit for the state of the GPIO input. When GPIO_DIR has channel configured as an output (1), write 0 for Low output/write 1 for High output: Data bits [7:0] correspond to one of eight channels GPIO_CH [8:1] respectively.

Note
Reading this register returns the output to the I/O pin of a specific channel and does not return the value set to the register. Because of this, if there is impedance to the pin it may not return the proper setting. For example, if the channel is set to drive high and some impedance causes it to drive low, then this register will read low (0). To guarantee the correct setting is read, please refer to the GPIO Loopback register.

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.
