START/STOP PERIOD REGISTER (0x1A)

This register is used to control the soft-start and soft-stop period when starting up or shutting down channels.

The value in this register determines the time for which the PWM inputs switch at 50% duty cycle. This helps

reduce pops and clicks at start-up and shutdown.

D7 is used to configure the output stage in a bridge-tied mode or a single-ended mode.
