SDO2_1
Output
GPIO
disconnected
Serial Data Output 2—When programmed as a transmitter,
SDO2_1 is used to transmit data from the TX2 serial
transmit shift register.
SDI3_1
Input
Serial Data Input 3—When programmed as a receiver,
SDI3_1 is used to receive serial data into the RX3 serial
receive shift register.
PE9
Input, output, or
disconnected
Port E9—When the ESAI_1 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.
