PIFn
Pin Interrupt Channel n Flag
If the edge trigger is selected, this flag will be set by hardware if the channel n of pin interrupt
detects an enabled edge trigger. This flag should be cleared by software.
If the level trigger is selected, this flag follows the inverse of the input signal’s logic level on the
channel n of pin interrupt. Software cannot control it.
