Signal Description

SDO4

SDI1

PC7

Output

Input

Input, Output, or

Disconnected

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

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

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

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

Port C 7—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.

This input is 5 V tolerant.

SDO3

SDI2

PC8

Output

Input

Input, Output, or

Disconnected

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

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

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

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

Port C 8—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.

This input is 5 V tolerant.
