S Timing

I
S 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 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 the bit clock. The
TAS5508 masks unused trailing data bit positions.
