RESET Condition: Resume Reset, INIT(CR40.7), or both VID detect no CPU.
Writing Tolerance register will force VCORE Limit Generator generate new voltage limit for VCORE.
For example, writing CR[FDh] with 01 in VRM 10.1 mode will result in VCORE limit registers
CR[2B/2C/2D/2E] become Voltage(VID) +/- Tolerance + 12.5mV.

Default 0, these 2 bits record last WDT stage for BIOS readout.
1: a hard timeout occurs. This bit will be cleared while reading.
Time to issue WDTRST#. Unit in minutes.
Reserve.
The information is used to help BIOS to identify WDT timeout
issue.
1: a soft timeout occurs. This bit will be cleared while reading.
Write 00h will disable the timer.
