16.13.13 Register C8h PWM1 Control 1
This register can bind PWM1 to several different control sources. The temperature zones control the PWM duty cycle using the
table lookup function. The PROCHOT and VRD_HOT inputs control the PWM using the ramp up/ramp down functions. If multiple
control sources are bound to PWM1, the largest duty cycle being requested will be used.
