TEMP_SENSE

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 used to

monitor the temperature of the die. Must be bypassed with a

0.01μF capacitor.

CAN_RX

121

Schmitt

Input

Input,

pullup

enabled

FlexCAN Receive Data

— This is the CAN input. This pin has an

internal pullup resistor.

To deactivate the internal pullup resistor, set the CAN bit in the

SIM_PUDR register.

CAN_TX

enabled

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 pullup resistor, clear the appropriate bit

of the GPIOE_PUR register. See Part 6.5.6 for details.
