AFG GPIOEn
[1]
Data1
RW
0x0
Data for GPIO1 (Pin 46). 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
RW
0x0
Data for GPIO0 (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).
