SDO5
Output
GPIO
disconnected
Serial Data Output 5—When programmed as a transmitter,
SDO5 is used to transmit data from the TX5 serial transmit
shift register.
SDI0
Input
Serial Data Input 0—When programmed as a receiver,
SDI0 is used to receive serial data into the RX0 serial
receive shift register.
PC6
Input, output, or
disconnected
Port C6—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.
