I2S timing uses LRCLK to define when the data being transmitted is for the left channel and when it is for the

right channel. LRCLK is low for the left channel and high for the right channel. A bit clock running at 32, 48, or

64 × fS is used to clock in the data. There is a delay of one bit clock from the time the LRCLK signal changes

state to the first bit of data on the data lines. The data is written MSB first and is valid on the rising edge of bit

clock. The DAP masks unused trailing data-bit positions.

NOTE: All data presented in 2s-complement form with MSB first.
