MODE

7 BICLK_STRB: defines the bit clock edges:

0: strobe is falling edge, active edge is rising

1: strobe is rising edge, active edge is falling (default)

6 LRCLK_LEFT: defines the channel for the LR clock:

0: clock is low for left channel, high for right channel

1: clock is high for left channel, low for right channel (default)

5 SDATAO_ ACT: sets the behavior of pin SDATAO:

0: output is tristated when no data is sent (default)

1: output is never in tri-state (it is 0 when no data is sent)

4 MSB_FIRST: data alignment in the protocol for SDATAI and SDATAO:

0: LSB is the first bit

1: MSB is the first bit (default)

3:1 DATA_FORMAT[2:0]: serial interface protocol format:

000: left justified

001: I2S (default)

010: right justified

100: PCM no delay

101: PCM delay

111: DSP

0 MASTER_ MODE: selects serial interface master/slave mode:

0: slave

1: master (default)
