Payload
Data for GPIO1 (Pin 34). 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 33). 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).
