Signal Description

SDO5_1

SDI0_1

PE6

Output

Input

Input, output, or

disconnected

GPIO

disconnected

Serial Data Output 5_1—When programmed as a

transmitter, SDO5_1 is used to transmit data from the TX5

serial transmit shift register.

Serial Data Input 0_1—When programmed as a receiver,

SDI0_1 is used to receive serial data into the RX0 serial

receive shift register.

Port E6—When the ESAI_1 is configured as GPIO, this

signal is individually programmable as input, output, or

internally disconnected.

The default state after reset is GPIO disconnected.

SDO4_1

SDI1_1

PE7

Output

Serial Data Output 4_1—When programmed as a

transmitter, SDO4_1 is used to transmit data from the TX4

serial transmit shift register.

Serial Data Input 1_1—When programmed as a receiver,

SDI1_1 is used to receive serial data into the RX1 serial

receive shift register.

Port E7—When the ESAI_1 is configured as GPIO, this

signal is individually programmable as input, output, or

internally disconnected.

The default state after reset is GPIO disconnected.
