0: Normal Operation
1: Power Save Mode (Default)
When the SPPS bit = “1”, the Speaker-amp is in power-save-mode and the SPP pin becomes Hi-Z and SPN pin is
set to HVDD/2 voltage. When the PMSPK bit = “1”, this bit is valid. After the RESETN pin changes from “L” to
“H”, the PMSPK bit is “0”, which powers down Speaker-amp
