Legacy register holding temperature related constants for Platform use.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31 | 0h | RW/L | (LOCKED) When set, this entire register becomes read-only. |
| 30:24 | 0h | RO | TjMax Tcc Offset (TJ_MAX_TCC_OFFSET) Temperature offset in degrees (C) from the TJ Max. Used for throttling temperature. Will not impact temperature reading. If offset is allowed and set - the throttle will occur and reported at lower then Tj_max. |
| 23:16 | 0h | RO | Thermal Junction Maximum Temperature (TJMAX) This field indicates the maximum junction temperature, also referred to as the Throttle Temperature, TCC Activation Temperature or Prochot Temperature. This is the temperature at which the Adaptive Thermal Monitor is activated. |
| 15:8 | 0h | RO | Fan Temperature Offset (FAN_TEMP_TARGET_OFST) Fan Temperature Target Offset (a.k.a. T-Control) indicates the relative offset from the Thermal Monitor Trip Temperature at which fans should be engaged. |
| 7:0 | 0h | RO | Reserved |
