Key Input Interrupt (Key-on Wake-Up)
A key input 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 18, where an inter-
rupt request is generated by pressing one of the keys consisted as
an active-low key matrix which inputs to ports P20–P24.
