Controls the hysteresis for voltage limit comparisons. Also
selects filtered or unfiltered temperature usage for temperature
limit comparisons and fan control.
Enables smart tach detection. Also selects 0.5C or 1.0C
resolution for fan control.
Control the input threshold levels for the P1_VIDx, P2_VIDx
and GPIO_x inputs.
Controls the ramp rate of the PWM duty cycle when
VRDx_HOT is asserted, as well as the ramp rate when
PROCHOT exceeds the user threshold.
Fan Boost Hysteresis for zones 1 and 2
Fan Boost Hysteresis for zones 3 and 4
