Left-justified (LJ) 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 lines at the same time LRCLK

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

trailing data-bit positions.

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