Key Input Interrupt (Key-On Wake-Up)
A key-on wake-up interrupt request is generated by applying “L”
level to any pin of port P0 that has been set to input mode.
In other words, it is generated when the 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 provided as an active-low key matrix which uses
ports P00 to P03 as input ports.
