used to transmit data from the TX4 serial transmit shift register.
Serial Data Input 1—When programmed as a receiver, SDI1 is used
to receive serial data into the RX1 serial receive shift register.
Port C 7—When the ESAI is configured as GPIO, this signal is
individually programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
