Serial Data Output 2—When programmed as a transmitter,
SDO2_1 is used to transmit data from the TX2 serial
transmit shift register.
Serial Data Input 3—When programmed as a receiver,
SDI3_1 is used to receive serial data into the RX3 serial
receive shift register.
Port E9—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.
Serial Data Output 1—SDO1_1 is used to transmit data
from the TX1 serial transmit shift register.
Port E10—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.
Serial Data Output 0—SDO0_1 is used to transmit data
from the TX0 serial transmit shift register.
Port E11—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.
