Read ‘1’ if state transition is detected in corresponding GPIO channel
Write’1’ to clear the interrupt staus.

This register reflects the status of GPIO that has been configured as input. When
there is a change in GPIO state, the corresponding bit will be set to ‘1’ by hardware.
Writing ‘1’ to the corresponding bit clears it. Writing ‘0’ has no effect.
