SYSTIN temperature sensor High Limit
SYSTIN temperature sensor Hysteresis Limit
FAN1 Fan Count Limit
Note: It is the number of counts of the internal
clock for the Low Limit of the fan speed.
FAN2 Fan Count Limit
Note: It is the number of counts of the internal
clock for the Low Limit of the fan speed.
FAN3 Fan Count Limit
Note: It is the number of counts of the internal
clock for the Low Limit of the fan speed.

Setting all ones to the high limits for voltages and fans (0111 1111 binary for temperature) means
interrupts will never be generated except the case when voltages go below the low limits.

Bit 7-1: Read Only - Device ID<6:0>
Bit 0 : CPU Vcore ID [4]. The VID value is written by BIOS if the VID value can be detected. After the
VID value is written, Software/AP can use this information to identify the Vcore voltage of the
CPU.
