Each IO port has an associated bit field in this register.
The bit field reflects the IO port's interrupt line (bit field
i reflects 'gpio_interrupts[i]' for IO port i). The register is
used when the system uses a combined interrupt line
'gpio_interrupt'. The software ISR reads the register to
determine which IO port(s) is responsible for the
combined interrupt line. Once, the IO port(s) is
determined, the IO port's GPIO_PRT_INTR register is
read to determine the IO pin(s) in the IO port that
caused the interrupt.
'0': Port has no pending interrupt
'1': Port has pending interrupt
