S Shift
These bits control the offset of audio data in the audio frame for both input and output. The offset is defined as
the number of BCK from the starting (MSB) of audio frame to the starting of the desired audio sample.
Default value: 00000000
00000000: offset = 0 BCK (no offset)
00000001: ofsset = 1 BCK
00000010: offset = 2 BCKs
11111111: offset = 256 BCKs
