Right-Justified Timing

Right-justified (RJ) timing uses LRCLK to define when the data being transmitted is for the left channel and

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

or 64 times Fs is used to clock in the data. The first bit of data appears following the eighth bit-clock period

(for 24-bit data) after LRCLK toggles. In RJ mode, the last bit clock before LRCLK transitions always clocks

the LSB of data. The data is written MSB first and is valid on the rising edge of the bit clock. The TAS5036A

masks unused leading data bit positions. Master mode only supports a 64 times Fs bit clock.
