Serial Data Output 4—When programmed as a transmitter, SDO4
is used to transmit data from the TX4 serial transmit shift register.
Serial Data Input 1—When programmed as a receiver, SDI1 is
used to receive serial data into the RX1 serial receive shift register.
Port C7—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 3—When programmed as a transmitter, SDO3
is used to transmit data from the TX3 serial transmit shift register.
Serial Data Input 2—When programmed as a receiver, SDI2 is
used to receive serial data into the RX2 serial receive shift register.
Port C8—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.
