Undefined, always reads as 00h.
A 1 outputs a minimum 20 ms active low pulse on the Chassis Intrusion pin. The
register bit clears itself after the pulse has been output.
The VID<3:0> inputs from processor core power supplies to indicate the operating
voltage (e.g., 1.3 V to 3.5 V).
Sets counter prescaler for FAN1 speed measurement.
<5:4> = 00 – divide by 1
<5:4> = 01 – divide by 2
<5:4> = 10 – divide by 4
<5:4> = 11 – divide by 8
Sets counter prescaler for FAN2 speed measurement.
<7:6> = 00 – divide by 1
