Right-Justified Timing
Right-justified (RJ) timing uses an LRCLK to define when the data being transmitted is for the left channel and
when it is for the right channel. The 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 on the data 8-bit clock
periods (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 bit clock. The TAS5026
masks unused leading data bit positions. Master mode only supports a 64 times Fs bit clock.
