Bit Name R/W Description
0 ZN1 R/W If set, PWM1 will be bound to temperature zone 1.
1 ZN2 R/W If set, PWM1 will be bound to temperature zone 2.
2 ZNE R/W If set, PWM1 will be bound to temperature zone 3.
3 ZN4 R/W If set, PWM1 will be bound to temperature zone 4.
4 PH1 R/W If set, PWM1 will be bound to P1_PROCHOT.
5 PH2 R/W If set, PWM1 will be bound to P2_PROCHOT.
6 VRD1 R/W If set, PWM1 will be bound to VRD1_HOT1.
7 VRD2 R/W If set, PWM1 will be bound to VRD1_HOT2.
This register can bind PWM1 to several different control sources. The temperature zones control the PWM duty cycle using the
table lookup function. The Px_PROCHOT and VRDx_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.
