MGAIN2-0: MIC-Amp Gain Control (Table 19)
MGAIN1 bit is D5 bit of 03H.

When PMLO bit is “1”, DACL bit is enabled. When PMLO bit is “0”, the LOUT/ROUT pins go to AVSS.
DACS: Switch Control from DAC to Speaker-Amp
0: OFF (default)
1: ON
When DACS bit is “1”, DAC output signal is input to Speaker-Amp.
BEEPS: Switch Control from MIN pin to Speaker-Amp
0: OFF (default)
1: ON
When BEEPS bit is “1”, mono 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 on power-save mode. In this mode, SPP pin goes to Hi-Z and SPN
pin is 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”.
