Serial Data Output 4
—When programmed as a transmitter, SDO4 is 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 3.3V tolerant.
