Register Name
Signal Select 1
When the MOUT2 bit = “0”, the MOUT2 pin outputs VCOM voltage. The MOUT2 pin outputs signal at the
MOUT2 bit = “1”. This bit is valid at the PMSPK bit = “1”. Hi-Z is output at the PMSPK bit = “0”.
ALC2 output signal is mixed to Speaker-amp at the ALCS bit = “1”.
Mono BEEP signal (BEEPM pin) is mixed to Speaker-amp at the BPMSP bit = “1”.
Stereo BEEP signals (BEEPL/BEEPR pins) are mixed to Speaker-amp at the BPSSP bit = “1”.
DAC output signal is output through Mono Line Output (MOUT+/MOUT-pins) at the DAMO bit = “1”.
When the PSMO bit = “0”, Mono Line Output is in power save mode and the MOUT+ and MOUT- pins output
0.45 x AVDD voltage.
