SCK
Serial Clock.
Serial clock for SDATA pin which can be configured (via the M0, M1 and M2 pins) as an input
or output and can sample data on the rising or falling edge.As an output, SCK will contain 32
clocks for every audio sample.
7
FSYNC Frame Sync.
Delineates the serial data and may indicate the particular channel, left or right and may be an
input or output. The format is based on M0, M1 and M2 pins.
