START/STOP PERIOD REGISTER (0x1A)
www.ti.com............................................................................................................................................. SLOS606D – MARCH 2009 – REVISED SEPTEMBER 2009
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.
