SDO5

Output

GPIO

disconnected

Serial Data Output 5—When programmed as a transmitter,

SDO5 is used to transmit data from the TX5 serial transmit

shift register.

SDI0

Input

Serial Data Input 0—When programmed as a receiver,

SDI0 is used to receive serial data into the RX0 serial

receive shift register.

PC6

Input, output, or

disconnected

Port C6—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.

SDO4

Output

GPIO

disconnected

Serial Data Output 4—When programmed as a transmitter,

SDO4 is used to transmit data from the TX4 serial transmit

shift register.

SDI1

Input

Serial Data Input 1—When programmed as a receiver,

SDI1 is used to receive serial data into the RX1 serial

receive shift register.

PC7

Input, output, or

disconnected

Port C7—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.

SDO3

Output
