MGAIN2, MGAIN0: MIC-Amp Gain Control (Table 18)
MGAIN1 bit is D5 bit of 03H. Default: “001H” (+20.0dB)
PMMP: Power Supply Control for Microphone
0: OFF (Default)
1: ON
When PMADC bit is “1”, PMMP bit is enabled.
DACA: Switch Control from DAC to Mono Line Output
0: OFF (Default)
1: ON
When PMAO bit is “1”, DACA bit is enabled. When PMAO bit is “0”, the AOUT pin 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 BEEP pin to Speaker-Amp
0: OFF (Default)
1: ON
When BEEPS bit is “1”, BEEP 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, 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 “H”,
Speaker-Amp is in power-down mode since PMSPK bit is “0”.
