SDO2
Output
GPIO
disconnected
Serial Data Output 2—When programmed as a transmitter,
SDO2 is used to transmit data from the TX2 serial transmit
shift register
SDI3
Input
Serial Data Input 3—When programmed as a receiver,
SDI3 is used to receive serial data into the RX3 serial
receive shift register.
PC9
Input, output, or
disconnected
Port C9—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.
Internal Pull down resistor.
This input is 5 V tolerant.
