Temperature Sense Diode — This signal connects to an
on-chip diode that can be connected to one of the ADC inputs
and is used to monitor the temperature of the die. Must be
bypassed with a 0.01 μF capacitor.

Input,
pull-up
enabled
FlexCAN Receive Data — This is the CAN input. This pin has
an internal pull-up resistor.
To deactivate the internal pull-up resistor, set the CAN bit in the
SIM_PUDR register.
