Return the last value written to bit #Y.
Writing:
1 = 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.
0 = For GPIO_IPMSK{X} = 1, interrupt will occur upon GPIO[X]
low or negative edge; for GPIO_IPMSK{X} = 0, interrupt will
not occur upon GPIO[X] low or negative edge.
