Signal Groupings

Freescale Semiconductor

SDO5_1

Output

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.

SDI0_1

Input

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.

PE6

Input, output, or

disconnected

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.

Internal Pull down resistor.

This input is 5 V tolerant

SDO4_1

Output

GPIO

disconnected

Serial Data Output 4_1—When programmed as a

transmitter, SDO4_1 is used to transmit data from the TX4

serial transmit shift register.

SDI1_1

Input

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.

PE7

Input, output, or

disconnected

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.

Internal Pull down resistor.

This input is 5 V tolerant.

SDO3_1

Output

GPIO

disconnected

Serial Data Output 3—When programmed as a transmitter,

SDO3_1 is used to transmit data from the TX3 serial

transmit shift register.

SDI2_1

Input

Serial Data Input 2—When programmed as a receiver,

SDI2_1 is used to receive serial data into the RX2 serial

receive shift register.

PE8

Input, output, or

disconnected

Port E8—When the ESAI is configured as GPIO, this signal

is individually programmable as input, output, or internally

disconnected.
