ADCx Input Select, Invert & Mute (Address 07h)
ADCX Input Select Bits (AINX_MUX[1:0])
Default: 00
Function:
Selects the specified analog input signal into ADCx. The microphone pre-amplifier is only available when
PDN_PGAx is disabled. See
ADCX Invert Signal Polarity (INV_ADCX)
Default: 0
0 - Disabled
1 - Enabled
Function:
When enabled, this bit will invert the signal polarity of the ADC x channel.
ADCX Channel Mute (ADCX_MUTE)
Default: 0
0 - Disabled
1 - Enabled
Function:
The output of channel x ADC will mute when enabled. The muting function is affected by the ADCx Soft bit
(SOFT).
