The SPI could function as an audio I
setting the I2SMOD bit in the SPI_I2SCFGR register). This interface uses almost the same
pins, flags and interrupts as the SPI.

SD: Serial Data (mapped on the MOSI pin) to transmit or receive the two time-
multiplexed data channels (in simplex mode only).
WS: Word Select (mapped on the NSS pin) is the data control signal output in master
mode and input in slave mode.
CK: Serial Clock (mapped on the SCK pin) is the serial clock output in master mode
and serial clock input in slave mode.
