Serial Data Output 2—When programmed as a transmitter,

SDO2_1 is used to transmit data from the TX2 serial

transmit shift register.

Serial Data Input 3—When programmed as a receiver,

SDI3_1 is used to receive serial data into the RX3 serial

receive shift register.

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.
