MGAIN3-2, MGAIN0: MIC-amp Gain control (Table 20)
MGAIN1 bit is located at D5 bit of 03H. Default: “0001” (+20.0dB)
PMMP: MPI pin Power Control
0: OFF (default)
1: ON
DACA: Switch Control from DAC to mono line amp
0: OFF (default)
1: ON
When PMAO bit is “1”, DACA bit is enabled. When PMAO bit is “0”, the AOUT pin goes VSS1.
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, 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”.
