Production Data
The polarity of each ADC output signal can be changed under software control using the
ADCL_DATINV and ADCR_DATINV register bits. The AIFADCL_SRC and AIFADCR_SRC register
bits may be used to select which ADC is used for the left and right digital audio interface data. These
register bits are described in Table 19.
Table 19 ADC Routing and Control
The input data source for each DAC can be changed under software control using register bits
DACL_SRC and DACR_SRC. The polarity of each DAC input may also be modified using register
bits DACL_DATINV and DACR_DATINV. These register bits are described in Table 20.
