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

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.

SDO1

Output

The default state after reset is GPIO disconnected.

Internal Pull down resistor.

This input is 5 V tolerant.

GPIO

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

disconnected TX1 serial transmit shift register.

PC10

Input, output, or

disconnected

Port C10—When the ESAI is configured as GPIO, this signal is

individually programmable as input, output, or internally

disconnected.

SDO0

Output

The default state after reset is GPIO disconnected.

Internal Pull down resistor.

This input is 5 V tolerant.

GPIO

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

disconnected TX0 serial transmit shift register.

PC11

Input, output, or

disconnected

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.
