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.
Internal Pull down resistor.
This input is 5 V tolerant
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.
Internal Pull down resistor.
This input is 5 V tolerant.
Serial Data Output 3—When programmed as a transmitter,
SDO3_1 is used to transmit data from the TX3 serial
transmit shift register.
Serial Data Input 2—When programmed as a receiver,
SDI2_1 is used to receive serial data into the RX2 serial
receive shift register.
Port E8—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.
