Key Input Interrupt (Key-on Wake Up)
A Key input interrupt request is generated by applying
“
L
”
level to
any pin of port P3 that have been set to input mode. In other
words, it is generated when the logical AND of all port P3 input
goes from
“
1
”
to
“
0
”
. An example of using a key input interrupt is
shown in Figure 18, where an interrupt request is generated by
pressing one of the keys consisted as an active-low key matrix
which inputs to ports P3
