Key Input Interrupt (Key-on Wake Up)
A Key-on wake up interrupt request is generated by applying
L
level voltage to any pin of port P3 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
pressing one of the keys consisted as an active-low key matrix
which inputs to ports P3
0
