Defines if the TX Audio clocks are
slave or master.
0 - slave mode.
1 - master mode.
Determines the timing of the lrckt with respect to the sdox
data outputs.
0 - Transition of lrckt occurs together with the first data bit.
1 - Transition of lrckt occurs one bitclk cycle before the first
sdox data bit. This is I
Defines polarity of the TX bitclk.
1 - Positive clock polarity. The lrckt and sdox lines change
synchronously with the positive edge of the bitclk and are
considered valid during negative transitions.
0 - Negative clock polarity. The lrckt and sdox lines change
synchronously with the negative edge of the bitclk and are
considered valid during positive transitions.
Defines the polarity of lrckt.
0 - if lrckt is low, then it is the left word, if lrckt is high, then
it is the right word.
1 - if lrckt is low, then it is the right word, if lrckt is high,
then it is the left word.
