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 PORT71

has a falling edge signal, it will generate a interruption.

Interrupt sources which has the same interrupt flag. Any pin from PORT72

has a falling edge signal, 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.

Low reset
