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.
