DACL: DAC Output Signal to Stereo Line Amp Control
0: OFF (default)
1: ON
When PMLO bit = “1”, this bit setting is enabled. LOUT and ROUT pins output VSS1 when PMLO bit = “0”.
DACS: Signal 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.
BEEPL: Signal Switch Control from the MIN pin to Lineout
0: OFF (default)
1: ON
This setting is valid when PMBP bit = “1”. Set BEEP signal input mode by BPM bit. The signal from the MIN
pin is input to lineout by BEEPL bit = “1”.
BEEPS: Signal Switch Control from the MIN pin to Speaker-Amp
0: OFF (default)
1: ON
This setting is valid when PMBP bit = “1”. Set BEEP signal input mode by BPM bit. The signal from the MIN
pin is input to lineout by BEEPS bit = “1”.
LOPS: Stereo Line Output Power Save
0: Normal Operation (default)
1: Power Save Mode
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 the
SPN pin outputs AVDD/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”.
