TRANSMITTER SERIAL CLOCK (SCKT)

SCKT is a bidirectional pin providing the transmitters serial bit clock for the ESAI interface.
The direction of this pin is determined by the TCKD bit in the TCCR register. The SCKT is a
clock input or output used by all the enabled transmitters in the asynchronous mode (SYN=0)
