Serial Data Output 2—When programmed as a transmitter,
SDO2 is used to transmit data from the TX2 serial transmit
shift register
Serial Data Input 3—When programmed as a receiver,
SDI3 is used to receive serial data into the RX3 serial
receive shift register.
Port C9—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 1—SDO1 is used to transmit data from
the TX1 serial transmit shift register.
Port C10—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 is used to transmit data from
the TX0 serial transmit shift register.
Port C11—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.
