I2S 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. From the time the LRCLK signal changes state to the first bit of data on the data lines is a
delay of one bit clock. The data is written MSB first and is valid on the rising edge of the bit clock. The
TAS5518C masks unused trailing data bit positions.
