GPIO Interrupt Request Status Register (GPIO[23:20])

GPIO23 Interrupt Status
When this bit is inactive (a zero), it
indicates that no interrupt
has been configured and detected
on the associated signal.
When this bit is active (an one), it
indicates that an interrupt
request has been configured and
detected on the associated
signal. Once this bit is active (an
one), software must write an
one to this bit to clear it inactive (a
zero), otherwise this bit and
the associated GPIO Interrupt
Request will remain active (an
one).
