When MICAD bit is “1”, the ALC1 output signal is input to ADC.
When PMMIC bit is “1”, MPWR bit is enabled.
When PMSPK bit is “1”, DACM bit is enabled. When PMSPK bit is “0”, MOUT pin is Hi-Z state.
When PMAO bit is “1”, DACA bit is enabled. When PMAO bit is “0”, the AOUT pin is AVSS.
When ALC2S bit is “1”, the ALC2 output signal is input to Speaker-Amp.
When BEEPS bit is “1”, the beep signal is input to Speaker-Amp.
When SPPS bit is “1”, the Speaker-amp is in power-save-mode and the SPP pin becomes Hi-z and SPN pin is
set to SVDD/2 voltage. When the PMSPK bit = “1”, this bit is valid. After the PDN pin changes from “L” to
“H”, the PMSPK bit is “0”, which powers down Speaker-amp.
