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.

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
