FlexCAN Receive Data — This is the CAN input. This pin has an
internal pull-up resistor.
Port C GPIO — This GPIO pin can be individually programmed as an
input or output pin.
In the 56F8322, the default state after reset is CAN_RX.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.

FlexCAN Transmit Data — CAN output with internal pull-up enable
at reset.*
* Note: If a pin is configured as open drain output mode, internal
pull-up will automatically be disabled when it outputs low. Internal
pull-up will be enabled unless it has been manually disabled by
clearing the corresponding bit in the PUREN register of the GPIO
module, when it outputs high.
If a pin is configured as push-pull output mode, internal pull-up will
automatically be disabled, whether it outputs low or high.
Port C GPIO — This GPIO pin can be individually programmed as an
input or output pin.
In the 56F8322, the default state after reset is CAN_TX.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.
