<Note> PORT70 ~ PORT73 's wakeup function is controlled by IOCF bit3 and ENI instruction. They are
falling edge trigger.
PORT74 ~ PORT76 's wakeup function is controlled by IOCF bit4 and ENI instruction. They are falling
edge trigger.
PORT77 's wakeup function is controlled by IOCF bit5 and ENI instruction. It's falling edge or rising edge
trigger (controlled by CONT register).
