Return 0.
0 = Mask off the function associated with GPIO_IP{X}.
1 = Enable the function associated with GPIO_IP{X}.
Return the last value written to bit #Y.
1 = For GPIO_IPMSK{X} = 1, interrupt will occur upon GPIO[X]
0 = For GPIO_IPMSK{X} = 1, interrupt will occur upon GPIO[X]
high or positive edge; for GPIO_IPMSK{X} = 0, interrupt will
not occur upon GPIO[X] high or positive edge.
low or negative edge; for GPIO_IPMSK{X} = 0, interrupt will
not occur upon GPIO[X] low or negative edge.
