PE0

Input, output, or

disconnected

GPIO

disconnected

Port E 0—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 cannot tolerate 5 V.

SCKT_1

Input or output

GPIO

disconnected

Transmitter Serial Clock_1—This signal provides the serial bit rate clock

for the ESAI. SCKT is a clock input or output used by all enabled

transmitters and receivers in synchronous mode, or by all enabled

transmitters in asynchronous mode.

PE3

Input, output, or

disconnected

GPIO

disconnected

Port E 3—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 cannot tolerate 5 V.

SDO5_1

Output

GPIO

disconnected

Serial Data Output 5_1—When programmed as a transmitter, SDO5 is

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

SDI0_1

Input

GPIO

disconnected

Serial Data Input 0_1—When programmed as a receiver, SDI0 is used to

receive serial data into the RX0 serial receive shift register.

PE6

Input, output, or

disconnected

GPIO

disconnected

Port E 6—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 cannot tolerate 5 V.

SDO4_1

Output

GPIO

disconnected

Serial Data Output 4_1—When programmed as a transmitter, SDO4 is

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

SDI1_1

Input

GPIO

disconnected

Serial Data Input 1_1—When programmed as a receiver, SDI1 is used to

receive serial data into the RX1 serial receive shift register.

PE7

Input, output, or

disconnected

GPIO

disconnected

Port E 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.
