Data for GPIO3 (Pin 47/EAPD). 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).

configured as Sticky (edge-sensitive) input,
it can be cleared by writing zero (one) here
when the corresponding Polarity Control bit
is zero (one).
