Notes
If the interrupt is enabled on this line in the EXTI_IMR, writing
a 1 to this bit when it is at '0' sets the corresponding pending
bit in EXTI_PR resulting in an interrupt request generation.
This bit is cleared by clearing the corresponding bit in the
EXTI_PR register (by writing a 1 into the bit)
