PWM SHUTDOWN GROUP REGISTER (0x19)

Settings of this register determine which PWM channels are active. The value should be 0x30 for BTL mode and

0x3A for PBTL mode. The default value of this register is 0x30. The functionality of this register is tied to the

state of bit D6 in the system control register.

This register defines which channels belong to the shutdown group (SDG). If a 1 is set in the shutdown group

register, that particular channel is not started following an exit out of all-channel shutdown command (if bit D6 is

set to 0 in system control register 2, 0x05).
