MOUT2: MOUT2 Output Enable (Mixing = (L+R)/2)
0: OFF (Default)
1: ON
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”.
ALCS: ALC2 to Speaker-amp Enable
0: OFF (Default)
1: ON
ALC2 output signal is mixed to Speaker-amp at the ALCS bit = “1”.
BPMSP: BEEPM to Speaker-amp Enable
0: OFF (Default)
1: ON
Mono BEEP signal (BEEPM pin) is mixed to Speaker-amp at the BPMSP bit = “1”.
BPSSP: BEEPL/BEEPR to Speaker-amp Enable
0: OFF (Default)
1: ON
Stereo BEEP signals (BEEPL/BEEPR pins) are mixed to Speaker-amp at the BPSSP bit = “1”.
MICM: Switch Control from Mic In to Mono Mixer.
0: OFF (Default)
1: ON
IPGA output signal is output through Mono Line Output (MOUT+/MOUT
pins) at the MICM bit = “1”.
DAMO: DAC to MOUT+/MOUT
Enable
0: OFF (Default)
1: ON
DAC output signal is output through Mono Line Output (MOUT+/MOUT
pins) at the DAMO bit = “1”.
PSMO: MOUT+/MOUT
Output Enable (Mixing = (L+R)/2)
0: Power Save Mode (Default)
1: Normal Operation
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.
MOGN: Gain control for mono output
0: +6dB (Default)
1:
17dB
