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.
