42/55

ADC_CONF

Address: 0xBC (188)

Type: R/W

Software Reset: 0x00

Hardware Reset: 0x00

Using this register the ADC input interface can be configured as follow:

AIIS: ADC I2S mode

0 = sample word must be aligned with LRCK (no I2S mode)

1 = sample word not aligned with LRCK (I2S compliant mode)

ADC: ADC Data Config.

0 = sample word is LSB first

1 = sample word is MSB first

ASCP: ADC Serial Clock Polarity

0 = Data is sampled on rising edge

1 = Data is sampled an falling edge

ALRCP: ADC Left/Right Clock Polarity

ALRCS: ADC Left/Right Clock Start value. This two

bits permit to determine Left/Right clock

usage according to the following table:
