Key Input Interrupt (Key-on Wake-Up)
A key input interrupt request is generated by detecting the falling
edge from any pin of ports P00–P03, P54–P57 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 17, where an interrupt request is generated by press-
ing one of the keys consisted as an active-low key matrix which in-
puts to ports P54–P57.
