Key Input Interrupt (Key-on wake-up)
A Key-on wake-up interrupt request is generated by applying a
falling edge to any pin of port P2 that have been set to input mode.
In other words, it is gener1ated when AND of input level goes from
“1” to “0”. An example of using a key input interrupt is shown in
Figure 21, where an interrupt request is generated by pressing
one of the keys consisted as an active-low key matrix which inputs
to ports P20–P23.
