SETUP REGISTERS

x Special Function Control 1 BCh 00h Controls the hysteresis for voltage limit comparisons. Also

selects filtered or unfiltered temperature usage for temperature

limit comparisons and fan control.

x Special Function Control 2 BDh 00h Enables smart tach detection. Also selects 0.5˚C or 1.0˚C

resolution for fan control.

x GPI / VID Level Control BEh 00h Control the input threshold levels for the P1_VIDx, P2_VIDx

and GPIO_x inputs.

x PWM Ramp Control BFh 00h 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.

x Fan Boost Hysteresis (Zones 1/2) C0h 44h Fan Boost Hysteresis for zones 1 and 2

x Fan Boost Hysteresis (Zones 3/4) C1h 44h Fan Boost Hysteresis for zones 3 and 4

x Zones 1/2 Spike Smoothing Control C2h 00h Configures Spike Smoothing for zones 1 and 2

x Zones 1/2 MinPWM and Hysteresis C3h N/D Controls MinPWM and hysteresis setting for zones 1 and 2

auto-fan control

x Zones 3/4 MinPWM and Hysteresis C4h N/D Controls MinPWM and hysteresis setting for zones 3 and 4

auto-fan control

GPO C5h 00h Controls the output state of the GPIO pins

PROCHOT Override

C6h 00h Allows manual assertion of P1_PROCHOT or P2_PROCHOT

PROCHOT Time Interval C7h 11h Configures the time window over which the PROCHOT inputs

are measured

x PWM1 Control 1 C8h 0Fh Controls PWM control source bindings.

x PWM1 Control 2 C9h 00h Controls PWM override and output polarity

x PWM1 Control 3 CAh 00h Controls PWM spin-up duration and duty cycle

x PWM1 Control 4 CBh 00h Frequency control for PWM1.

x PWM2 Control 1 CCh 0Fh Controls PWM control source bindings.

x PWM2 Control 2 CDh 00h Controls PWM override and output polarity

x PWM2 Control 3 CEh 00h Controls PWM spin-up duration and duty cycle

x Special FunctionPWM2 Control 4 CFh 00h Frequency control for PWM2
