- Implement a single function named gpio_interrupt_handler(). This
will need to manually check GPIO_STATUS_REG and clear any status
will need to manually check GPIO.STATUS and clear any status
bits after handling interrupts. This gives you full control, but
you can't combine it with the first approach.
