Signal Description

GPIO

Serial Data Output 5—When programmed as a transmitter, SDO5

disconnected is used to transmit data from the TX5 serial transmit shift register.

GPIO

Serial Data Input 0—When programmed as a receiver, SDI0 is

disconnected used to receive serial data into the RX0 serial receive shift register.

GPIO

disconnected

Port C 6—When the ESAI is configured as GPIO, this signal is indi-

vidually programmable as input, output, or internally disconnected.

The default state after reset is GPIO disconnected.

This input is 5 V tolerant.

GPIO

Serial Data Output 4—When programmed as a transmitter, SDO4

disconnected is used to transmit data from the TX4 serial transmit shift register.

GPIO

Serial Data Input 1—When programmed as a receiver, SDI1 is

disconnected used to receive serial data into the RX1 serial receive shift register.

GPIO

disconnected

Port C 7—When the ESAI is configured as GPIO, this signal is indi-

vidually programmable as input, output, or internally disconnected.

The default state after reset is GPIO disconnected.

This input is 5 V tolerant.

GPIO

Serial Data Output 3—When programmed as a transmitter, SDO3

disconnected is used to transmit data from the TX3 serial transmit shift register.

GPIO

Serial Data Input 2—When programmed as a receiver, SDI2 is

disconnected used to receive serial data into the RX2 serial receive shift register.

GPIO

disconnected

Port C 8—When the ESAI is configured as GPIO, this signal is indi-

vidually programmable as input, output, or internally disconnected.

The default state after reset is GPIO disconnected.

This input is 5 V tolerant.

GPIO

Serial Data Output 2—When programmed as a transmitter, SDO2

disconnected is used to transmit data from the TX2 serial transmit shift register

GPIO

Serial Data Input 3—When programmed as a receiver, SDI3 is

disconnected used to receive serial data into the RX3 serial receive shift register.

GPIO

disconnected

Port C 9—When the ESAI is configured as GPIO, this signal is indi-

vidually programmable as input, output, or internally disconnected.

The default state after reset is GPIO disconnected.

This input is 5 V tolerant.
