◆ exti_attach_interrupt()

void exti_attach_interrupt	(	afio_exti_num	num,
		afio_exti_port	port,
		Handler	handler,

	)

Register a handler to run upon external interrupt.

This function assumes that the interrupt request corresponding to the given external interrupt is masked.

Parameters

num	External interrupt line number.
port	Port to use as source input for external interrupt.
handler	Function handler to execute when interrupt is triggered.
mode	Type of transition to trigger on, one of: EXTI_RISING, EXTI_FALLING, EXTI_RISING_FALLING.
