Setting up Timer Module

[Dick Ivers]

Bruce,

Questions about your code for the 12F1822. Yes, I looked it up and there are some new chips that have auto context save/restore.

Does the interrupt handler have to be written in ASM? Not that it's a problem, the routines are usually short and simple. Also, can more than one type of interrupt be running together?

No it doesn't necessarily have to be in assembler, but it's a lot faster if it is. If you prefer to use BASIC then look into using DT_INTs.

Yes - you can have every interrupt that's available enabled. You just need to check in the interrupt handler to see which one triggered the interrupt.
