Right-justified (RJ) 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 high for the left channel and low for the right channel. A bit clock running at

32, 48, or 64 × fS is used to clock in the data. The first bit of data appears on the data line 8 bit-clock periods (for

24-bit data) after LRCLK toggles. In RJ mode, the LSB of data is always clocked by the last bit clock before

LRCLK transitions. The data is written MSB first and is valid on the rising edge of bit clock. The DAP masks

unused leading data bit positions.
