6.6.4 GPIO Interrupt Status for Rising edge register (IO0IntStatR - 0xE002 8084
6.6.5 GPIO Interrupt Status for Falling edge register (IO0IntStatF - 0xE002 8088
6.6.6 GPIO Interrupt Clear register (IO0IntClr - 0xE002 808C and IO2IntClr -
and IO2IntStatR - 0xE002 80A4)
Each bit in these read-only registers indicates the rising edge interrupt status for the
corresponding port.
Table 178. GPIO Status for Rising edge register (IO0IntStatR - address 0xE002 8084 and
and IO2IntStatF - 0xE002 80A8)
Each bit in these read-only registers indicates the rising edge interrupt status for the
corresponding port.
Table 179. GPIO Status for Falling edge register (IO0IntStatF - address 0xE002 8088 and
0xE002 80AC)
Writing a 1 into each bit in these write-only registers clears any interrupts for the
corresponding GPIO port pin.

Clear GPIO port Interrupt. Bit 0 in IOxIntClr corresponds to pin
Px.0, bit 31 in IOxIntClr corresponds to pin Px.31.
Corresponding bit in IOxIntStatR and/or IOxIntStatF is
unchanged.
Corresponding bit in IOxIntStatR and IOxStatF is cleared to 0.
Rising Edge Interrupt status. Bit 0 in IOxIntStatR corresponds to
pin Px.0, bit 31 in IOxIntStatR corresponds to pin Px.31.
Rising edge has not been detected on the corresponding pin.
An interrupt is generated due to a rising edge on the
corresponding pin.
Falling Edge Interrupt status. Bit 0 in IOxIntStatF corresponds to
pin Px.0, bit 31 in IOxIntStatF corresponds to pin Px.31.
Falling edge has not been detected on the corresponding pin.
An interrupt is generated due to a falling edge on the
corresponding pin.
