When DACS bit is “1”, DAC output signal is input to Speaker-Amp.
SPPSN: Speaker-Amp Power-Save Mode
0: Power-Save Mode (default)
1: Normal Operation
When SPPSN bit is “0”, Speaker-Amp is in power-save mode. In this mode, the SPP pin goes to Hi-Z and
outputs SVDD/2 voltage. When PMSPK bit = “1”, SPPSN bit is enabled. After the PDN pin is set to “L”,
Speaker-Amp is in power-down mode since PMSPK bit is “0”.
