Schmitt

Input

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.

Input

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.

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.

IRQA

Schmitt

Input

External Interrupt Request A and B — The IRQA and IRQB

inputs are asynchronous external interrupt requests during Stop

and Wait mode operation. During other operating modes, they

are synchronized external interrupt requests, which indicate an

external device is requesting service. They can be programmed

to be level-sensitive or negative-edge triggered.

To deactivate the internal pull-up resistor, set the IRQ bit in the

SIM_PUDR register. See Part 6.5.6 for details.
