When GPIO ports are used as interrupt ports, if the GPIO detects an interrupt, the interrupt is
notified to the INTC from the GPIO. However, it is indicated as a one-bit source in the INT2A0 or
INT2A1 register of the INTC. Referring to the on-chip module interrupt source register INT2B7.
Referring to the INTEVT code in the CPU can specify from which port group an interrupt is
generated.
