* If you want to use these external low priority interrupts or any of the
* peripheral interrupts then you must enable them in your initialization
* routine.  Innovation First, Inc. will not provide support for using these
* interrupts, so be careful.  There is great potential for glitchy code if good
* interrupt programming practices are not followed.  Especially read p. 28 of
* the "MPLAB(R) C18 C Compiler User's Guide" for information on context saving.
* CALLED FROM:   this file, InterruptVectorLow routine
