START/STOP PERIOD REGISTER (0x1A)

This register is used to control the soft-start and soft-stop period following an enter/exit all channel shut down

command or change in the PDN state. This helps reduce pops and clicks at start-up and shutdown. The times

are only approximate and vary depending on device activity level and I2S clock stability.
