[3]

Mask3

0x0

GPIO3 input type (when configured as

input):

0= Non-Sticky (level-sensitive);

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

0x0

GPIO2 input type (when configured as

input):

0= Non-Sticky (level-sensitive);

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

0x0

GPIO1 input type (when configured as

input):

0= Non-Sticky (level-sensitive);

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.

[0]

Mask0

0x0

GPIO0 input type (when configured as

input):

0= Non-Sticky (level-sensitive);

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.
