SPLN/SPRN pins output HVDD/2 voltage. When PMSPL or PMSPR bit is “1”, SPPSN bit is enabled.
When PMLO bit is “1”, DACL bit is enabled. When PMLO bit is “0”, the LOUT/ROUT pins go to VSS1.
When DACS bit is “1”, DAC output signal is input to Speaker-Amp.
When MINS bit is “1”, mono singal is input to Speaker-Amp.
When SPPSN bit is “0”, Speaker-Amp is in power-save mode. In this mode, SPLP/SPRP pins go to Hi-Z and
