Description
GPIO[X] Interrupt Polarity Mask, 31≥X≥16.
See specific GPIO_IPMSK{X},
bit
31≥X≥16,
Reading:
X = Y.
Return 0.
Writing:
0 = Mask off the function associated with GPIO_IP{X}.
1 = Enable the function associated with GPIO_IP{X}.
GPIO[X] Interrupt Polarity Control, 31≥X≥16.
Reading:
Return the last value written to bit #Y.
Writing:
15:0;
15≥Y≥0,
Y = Bit #
RW
See specific GPIO_IP{X},
bit
31≥X≥16,
X = Y+16.
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.
