In SSI devices, the PLM-to-PLM communication framework is used to securely propagate secondary SLR device temperatures to the primary SLR. The PLM then determines the overall device minimum and maximum temperatures and store the values. The temperature from each SLR is collected every 100 ms.
The overall device temperatures can be read from the following registers:
| Register | Address | Usage |
|---|---|---|
| SYSMON_TEST_ANA_CTRL0 | 0xF1270134 | Maximum device temperature |
| SYSMON_TEST_ANA_CTRL1 | 0xF1270138 | Minimum device temperature |
Note: The temperature values written to the
SYSMON_TEST_ANA_CTRL0/1 registers are in Q8.7 format in degrees Celsius.
