PORTB & PORTC interrupt
The PORTB and PORTC are used as port interrupt sources. Since PORT I/O is bit programmable I/O, so only the input port can
generate an external interrupt. Any one of the PORTB and PORTC input pin transitions from VDD to GND will generate an
interrupt request. And further falling edge transition would not be able to make interrupt request until all of the pins return to VDD.
Following is the port interrupt function block-diagram.
