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 0.5˚C or 1.0˚C
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
Configures Spike Smoothing for zones 1 and 2
Controls MinPWM and hysteresis setting for zones 1 and 2
auto-fan control
Controls MinPWM and hysteresis setting for zones 3 and 4
auto-fan control
Controls the output state of the GPIO pins
Allows manual assertion of P1_PROCHOT or P2_PROCHOT
Configures the time window over which the PROCHOT inputs
are measured
Controls PWM control source bindings.
Controls PWM override and output polarity
Controls PWM spin-up duration and duty cycle
Frequency control for PWM1.
Controls PWM control source bindings.
Controls PWM override and output polarity
Controls PWM spin-up duration and duty cycle
Frequency control for PWM2
