* 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.

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.

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.
