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 C7—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.

SDO3

Output

Internal Pull down resistor.

This input is 5 V tolerant.
