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).
Data for GPIO2 (Pin 45). 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).
