Output

Analog

Output

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.

Schmitt

Input

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.

Open

Drain

Output

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.

TC0 - 1 — Timer C, Channels 0 and 1

Port E GPIO — These GPIO pins can be individually

programmed as input or output pins.

At reset, these pins default to Timer functionality.

To deactivate the internal pull-up resistor, clear the appropriate

bit of the GPIOE_PUR register. See Part 6.5.6 for details.
