Once a pin is configured using pinMode as GPIO pins, it may no longer be available for use with any other peripherals (e.g., PWM, I2C, SPI, GPIO, etc.).


Interrupts
----------

.. code-block:: cpp

void attachInterrupt(pin_size_t interruptNumber, voidFuncPtr callback, PinStatus mode)

Interrupts are triggered only for the RISING or FALLING edge by the hardware. The LOW and HIGH modes are not natively supported but are internally mapped for compatibility:

- LOW mode is mapped to FALLING edge detection.
- HIGH mode is mapped to RISING edge detection.

This mapping simplifies compatibility but may not replicate the exact behavior of other Arduino platforms that natively support LOW and HIGH interrupt levels.
