GPIO[X] Interrupt Status, 31≥ ≥ ≥ ≥ X≥ ≥ ≥ ≥ 16.
Reading:
bit #Y = 0 = > No interrupt detected on GPIO[X].
bit #Y = 1 = > Interrupt input detected on GPIO[X].
Writing:
0 to bit #Y = > no effect
1 to bit #Y = > clear the interrupt on GPIO[X].
Note: If the interrupt is level-sensitive, the status bit will remain a 1 as
long as the interrupt resource is not removed. The bit can be cleared
only after the resource is removed and a 1 is written to it.
