BICLK_ STRB
Bit 7
LRCLK_LEFT
3:1 DATA_FORMAT[2:0]: serial interface protocol format:
7 BICLK_STRB: defines the bit clock edges:
6 LRCLK_LEFT: defines the channel for the LR clock:
5 SDATAO_ ACT: sets the behavior of pin SDATAO:
4 MSB_FIRST: data alignment in the protocol for SDATAI and SDATAO:
0 MASTER_ MODE: selects serial interface master/slave mode:
Bit 6
0: strobe is falling edge, active edge is rising
1: strobe is rising edge, active edge is falling (default)
0: clock is low for left channel, high for right channel
1: clock is high for left channel, low for right channel (default)
0: output is tri-stated when no data is sent (default)
1: output is never in tri-state (it is 0 when no data is sent)
0: LSB is the first bit
1: MSB is the first bit (default)
