PWM SHUTDOWN GROUP REGISTER (0x19)
Settings of this register determine which PWM channels are active. The default is 0x30 for two BTL output
channels and no external subwoofer output. The functionality of this register is tied to the state of bit D5 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 D5 is
set to 0 in system control register 2, 0x05).
