Key Input Interrupt (Key-on wake-up)
A Key-on wake up interrupt request is generated by applying “L”
level to any pin of port P2 that have been set to input mode. In
other words, it is generated when AND of input level goes from “1”
to “0”. An example of using a key input interrupt is shown in Figure
16, where an interrupt request is generated by pressing one of the
keys consisted as an active-low key matrix which inputs to ports
