Data3
Data for GPIO3 (Pin 47). If this GPIO bit is
RW
0x0
configured as Sticky (edge-sensitive) input, it can
be cleared by writing zero (one) here when the
corresponding Polarity Control bit is zero (one).
Data2
Data for GPIO2 (Pin 44). If this GPIO bit is
RW
0x0
configured as Sticky (edge-sensitive) input, it can
be cleared by writing zero (one) here when the
corresponding Polarity Control bit is zero (one).
