CS SERIAL IN / SC FRAME CLOCK
Positive supply for the digital section. Nominally +5 volts.
Ground for the digital section.
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. As an input, it does not need to be continuous and
can be up to 15 MHz.
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.
Audio data serial input pin.
Selects the format of FSYNC and the sample edge of SCK with respect to SDATA.
