The following figures illustrate the relationship between the SCLK, LRCLK, and the serial data I/O for the
different interface protocols. Note that there are always 64 SCLKs per LRCLK. The nondata bits are padded
with binary 0s.

Note the following characteristics of this protocol.
Left channel is received when LRCLK is high.
Right channel is received when LRCLK is low.
SDIN is sampled at the rising edge of SCLK.
