Rsvd

0x0

Reserved

[4]

Mask4

0x0

GPIO4 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.

[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.

[2]

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.
