PWM SHUTDOWN GROUP REGISTER (0x19)
Settings of this register determine which PWM channels are active. The default is 0x30 for two BTL output
channels. The functionality of this register is tied to the state of bit D5 in the system control register. This register
should be updated with a value of 0x00 before sending out the all-channel shutdown command to register 0x05.
