6.2.3
Power Down ADCx
Configures the power state of ADC channel x.
Notes:
1. The CS42L52 employs a clever scheme for controlling the power to the ADC when PASSTHRU
(“Passthru Analog” on page 52) and PDN_OVRD (“Power Down ADC Override” on page 43) are
enabled. Refer to the referenced application.
6.2.4
Power Down
Configures the power state of the entire CODEC.
6.3
Power Control 2 (Address 03h)
6.3.1
Power Down ADC Override
Configures an override of the power down control for ADCx.
6.3.2
Power Down MICx
Configures the power state of the microphone pre-amplifier for channel x.
6.3.3
