register
Reserved
Determines chargepump source when VDDC_ASSN_OVRD is set.
0x0 = VDDA
0x1 = VDDIO
Charge pump Source Assignment Override
0x0 = Charge pump source is automatically assigned based on higher of VDDA and
VDDIO
0x1 = the source of charge pump is manually assigned by VDDC_MAN_ASSN
If VDDIO and VDDA are both the same and greater than 3.1 V, VDDC_ASSN_OVRD
and VDDC_MAN_ASSN should be used to manually assign VDDIO as the source for
chargepump.
Reserved
Sets the VDDD lin. regulator output voltage in 50 mV steps. Must clear pwd_linreg_d
bit to enable this lin reg.
0x0 = 1.60
0xF = 0.85
Mute the headphone outputs
0x0 = Unmute
0x1 = Mute
Reserved
Select the ADC input.
0x0 = Microphone
0x1 = Line in
Enable the ADC analog zero cross detector (ZCD)
0x0 = ADC ZCD disabled
0x1 = ADC ZCD enabled
Mute the ADC analog volume
0x0 = Unmute
0x1 = Mute
