PORT6 can be INPUT or OUTPUT port each bit.
PORT7 can be INPUT or OUTPUT port each bit.
PORT9 can be INPUT or OUTPUT port each bit.
PORTC can be INPUT or OUTPUT port each bit.
Interrupt sources. Once PORT70 has a falling edge or rising edge signal
(controlled by CONT register), it will generate a interruption.
Interrupt sources which has the same interrupt flag. Any pin from PORT73
has a falling edge signal, it will generate a interruption.
