SLOT

ADCDAT TDM Slot Select

0 = ADCDAT data input on slot 0

1 = ADCDAT data input on slot 1

ADC_LRSWAP

Swap left/right ADC data on the interface

0 = Normal

1 = ADCDAT channels swapped

BCLK_INV

BCLK Invert

0 = BCLK not inverted

1 = BCLK inverted

DAC_LRSWAP

Swap left/right DAC data on the interface

0 = Normal

1 = DACDAT channels swapped

LRCLK_INV

Right, left and I2S modes

– LRCLK polarity

0 = normal LRCLK polarity

1 = invert LRCLK polarity

DSP Mode

– mode A/B select

0 = MSB is available on 2nd BCLK rising

edge after LRCLK rising edge (mode A)

1 = MSB is available on 1st BCLK rising

edge after LRCLK rising edge (mode B)

Table 90 Digital Audio Interface Data Control

AUDIO INTERFACE TRI-STATE

digital audio interface pins will be tri-stated by this function, regardless of the state of other registers

which control these pin configurations.

Control (2)

AIF_TRI

Audio Interface Tristate

0 = Audio interface pins operate normally

1 = ADCDAT is tri-stated; BCLK & LRCLK are

set as inputs

Table 91 Digital Audio Interface Tri-State Control

BCLK AND LRCLK CONTROL

The audio interface can be programmed to operate in master mode or slave mode using the MSTR

In master mode, the BCLK and LRCLK signals are generated by the WM8962 when any of the ADCs

or DACs is enabled. In slave mode, the BCLK and LRCLK clock outputs are disabled by default to

allow another digital audio interface to drive these pins.

Refer to “Clocking and Sample Rates” for

specific operating constraints in this configuration.
