Description
See specific GPIO_ISMMSK{X},
GPIO[X] Interrupt Sensitivity Mode Mask, 31≥X≥16.
bit
31≥X≥16,
Reading:
X = Y.
Return 0.
Writing:
0= Mask off the function associated with GPIO_ISMC{X}.
1 = Enable the function associated with GPIO_ISMC{X}.
GPIO[X] Interrupt Sensitivity Mode Control, 31≥X≥16.
Reading:
15:0;
15≥Y≥0,
Y = Bit #
RW
See specific GPIO_ISMC{X},
bit
31≥X≥16,
X = Y+16.
Return the last value written to bit #Y.
Writing:
1 = Interrupt input on GPIO[X] will be edge sensitive, if
GPIO_ISMMSK{X} = 1; don't care, otherwise.
0 = Interrupt input on GPIO[X] will be level sensitive, if
GPIO_ISMMSK{X} = 1; don't care, otherwise.
