SDATA
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, M2 and M3 pins.
Serial Clock.Serial clock for SDATA pin which can be configured (via the M0, M1, M2 and M3
pins) as an input or output and can sample data on the rising or falling edge. As an output, SCK
will generate 32 clocks for every audio sample. As an input, 32 SCK periods per audio sample
must be provided in all normal modes.
Serial Port Mode Selects.Selects the format of Fsync and the sample edge of SCK with respect
to SDATA.
Serial Data. Audio data serial output pin.
