Temperature Sense Diode
鈥?This signal connects to an on-chip
diode that can be connected to one of the ADC inputs and used to
monitor the temperature of the die. Must be bypassed with a 0.01碌F
capacitor.
FlexCAN Receive Data
鈥?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.
