Signal Description
PC6 Input, output, or
GPIO
Port C 6—When the ESAI is configured as GPIO, this signal is individually
disconnected disconnected programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
SDO4
Output
GPIO
Serial Data Output 4—When programmed as a transmitter, SDO4 is used to
disconnected transmit data from the TX4 serial transmit shift register.
SDI1
Input
GPIO
Serial Data Input 1—When programmed as a receiver, SDI1 is used to
disconnected receive serial data into the RX1 serial receive shift register.
PC7 Input, output, or
GPIO
Port C 7—When the ESAI is configured as GPIO, this signal is individually
disconnected disconnected programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
SDO3/SD
O3_1
Output
GPIO
disconnected
Serial Data Output 3—When programmed as a transmitter, SDO3 is used to
transmit data from the TX3 serial transmit shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Output 3.
SDI2/
SDI2_1
Input
GPIO
disconnected
Serial Data Input 2—When programmed as a receiver, SDI2 is used to
receive serial data into the RX2 serial receive shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Input 2.
PC8/PE8 Input, output, or
disconnected
GPIO
disconnected
Port C 8—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
When enabled for ESAI_1 GPIO, this is the Port E 8 signal.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
SDO2/
SDO2_1
Output
GPIO
disconnected
Serial Data Output 2—When programmed as a transmitter, SDO2 is used to
transmit data from the TX2 serial transmit shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Output 2.
SDI3/SDI3
_1
Input
GPIO
disconnected
Serial Data Input 3—When programmed as a receiver, SDI3 is used to
receive serial data into the RX3 serial receive shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Input 3.
PC9/PE9 Input, output, or
disconnected
GPIO
disconnected
Port C 9—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
When enabled for ESAI_1 GPIO, this is the Port E 9 signal.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
