When a GPIO port pin is used as an interrupt pin, the GPIO notifies the INTC of the interrupt
when the GPIO detects an interrupt. The INTC indicates the interrupt as a 1-bit source in INT2A0
or INT2A1. In this case, the port and the pin number which interrupts are generated from can be
identified by referring to INT2B6. Also, the ports can be specified by referring to the INTEVT
code.
