Mask3
GPIO3 input type (when configured as input):
0 = Non-Sticky (level-sensitive);
RW
0x0
1 = Sticky (edge-sensitive). Sticky inputs are
cleared by writing zero to corresponding bit of
GPIO Data register. GPIOPolarity determines
rising or falling edge sensitivity.
Mask2
GPIO2 input type (when configured as input):
0 = Non-Sticky (level-sensitive);
RW
0x0
1 = Sticky (edge-sensitive). Sticky inputs are
cleared by writing zero to corresponding bit of
GPIO Data register. GPIOPolarity determines
rising or falling edge sensitivity.
Mask1
GPIO1 input type (when configured as input):
0 = Non-Sticky (level-sensitive);
RW
0x0
1 = Sticky (edge-sensitive). Sticky inputs are
cleared by writing zero to corresponding bit of
GPIO Data register. GPIOPolarity determines
rising or falling edge sensitivity.
Mask0
GPIO0 input type (when configured as input):
0 = Non-Sticky (level-sensitive);
RW
0x0
1 = Sticky (edge-sensitive). Sticky inputs are
cleared by writing zero to corresponding bit of
GPIO Data register. GPIOPolarity determines
rising or falling edge sensitivity.
