Bit Descriptions:
Address:
Each bit in the register reports whether an interrupt would be signalled if the interrupt were
enabled for the corresponding port; a set bit indicates that an interrupt would be signalled.
The value reported is unaffected by whether interrupts are enabled or disabled. How a bit is
set depends on the interrupt type. If the interrupt is level sensitive active high, it reflects the
pin value. If level sensitive active low, it reflects the inverse of the pin value. If the interrupt is
edge triggered, the bit latches a one whenever the proper level change occurs. How a bit is
cleared also depends on the interrupt type. When an interrupt is level sensitive, it is cleared
when not asserted. When edge triggered, it is cleared by writing the corresponding bit in
GPIOxEOI. Note that the value of a bit is a debounced value if debouncing is enabled.
