Have a good read through this thread:

It shows exactly how to do this, including the complete code to set up and run the interrupt at a repetition rate of your choice.

Note that I originally developed the code for the Picaxe 28X1, but it should be possoble to adapt it to the 20X2 with only minimal changes (due to different clock frequencies).
