Signal Description

GPIO

disconnected

Serial Data Output 2—When programmed as a

transmitter, SDO2 is used to transmit data from the TX2

serial transmit shift register

Serial Data Input 3—When programmed as a receiver,

SDI3 is used to receive serial data into the RX3 serial

receive shift register.

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.

SDO1

PC10

Output

Input, output, or
