I'm using MC13224V, and need to connect a detector zero-cross.This integrated circuit has no external interrupt.What should I do?I connect the keyboard (KBI)? Thank you.

KBI4-7 can be used to generate interrupts from external sources. I have some code in Contiki that does this. See http://mc1322x.devl.org for more details.
The ADCs can also be programmed to auto-run and generate interrupts at specific levels.
You can probably use the TMR modules for what you want too.
