Payload
Data for GPIO1. 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. 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).
