Payload
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).
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).
