Data4

0x0

Data for GPIO4. If this GPIO bit is

configured as Sticky (edge-sensitive) input,

it can be cleared by writing zero (one) here

when the corresponding Polarity Control bit

is zero (one).

[3]

Data3

0x0

Data for GPIO3. If this GPIO bit is

configured as Sticky (edge-sensitive) input,

it can be cleared by writing zero (one) here

when the corresponding Polarity Control bit

is zero (one).

[2]

Data2

0x0

Data for GPIO2. If this GPIO bit is

configured as Sticky (edge-sensitive) input,

it can be cleared by writing zero (one) here

when the corresponding Polarity Control bit

is zero (one).

[1]

Data1

0x0

Data for GPIO1. If this GPIO bit is

configured as Sticky (edge-sensitive) input,

it can be cleared by writing zero (one) here

when the corresponding Polarity Control bit

is zero (one).

[0]

Data0

0x0

Data for GPIO0. If this GPIO bit is

configured as Sticky (edge-sensitive) input,

it can be cleared by writing zero (one) here

when the corresponding Polarity Control bit

is zero (one).
