Signal Description

SDO2

SDI3

PC9

Output

Input

Input, output, or

disconnected

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

disconnected

Internal Pull down resistor.

This input is 5 V tolerant.

GPIO

Serial Data Output 1—SDO1 is used to transmit data from

disconnected the TX1 serial transmit shift register.

Port C10—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.

SDO0

PC11

Output

Input, output, or

disconnected

Internal Pull down resistor.

This input is 5 V tolerant.

GPIO

Serial Data Output 0—SDO0 is used to transmit data from

disconnected the TX0 serial transmit shift register.

Port C11—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.
