_Temperature Readings Register_

Temperature Readings Register

The temperature registers provide the current, maximum (from power-up) and minimum (from power-up) for the processor and PCB for Zynq processor, and for the Slave processor.

These registers are only available on Xilinx Generation 5 platforms, and are periodically populated by the motherboard core application, which only runs in Petalinux and BareMetal. 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).

Function: Specifies the Measured Temperatures on Motherboard.

Type: signed byte (8-bits) for each temperature reading - Six (6) 32-bit words

Data Range: 0x0000 0000 to 0xFFFF 0000

Read/Write: R

Initialized Value: Value corresponding to the measured temperatures based on the table below.

Operational Settings: The 8-bit temperature readings are signed bytes. For example, if the following register contains the value 0x6955 0000:

The values would represent the following temperatures:

Temperature Measurements	Data Bits	Value	Temperature (Celsius)
Max Zynq Core Temperature	D31:D24	0x69	+105°
Max Zynq PCB Temperature	D23:D16	0x55	+85°
