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
GPIO2input 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
GPIO1input 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
