Once a complete set of left samples resides within the bottom of the active FIFOs, the SAIF
waits for the current collection of null samples (all left and right samples for a given time)
to complete before transmitting the left sample collection from the FIFOs.

For 16-bit mode, this field contains the entire right channel sample.
For 17-bit through 24-bit modes, this field contains 1 through 8 of the MSBs of the sample (either left or
right).
For 16-bit mode, this field contains the entire left channel sample.
For 17-bit through 24-bit modes, this field contains the 16 LSBs of the sample (either left or right).
