Hello,

I've very much enjoyed this list in the past and have
used it very much to answer many of my questions.  I
have one now that I haven't been able to solve yet.

I'm trying to port code from a 16f84-10 to a
16c622a/jw for more RAM.  I've taken the appropriate
porting precautions for the 622a.  The problem is that
the oscillators won't start up when I use the 622a.
For the equivalent program on the f84 the oscillators
work like a charm.

I've tried a 10MHz ceramic resonator and a 4MHz
crystal (with 2 22pF caps).  I've tried compiling with
both XC and HS (from a previous post).  I've tried on
a bread board and a soldered board.  I admit that I'm
not quite sure how oscillators work but I've read as
much as I can and can't understand what is happening
here.  Could there be a setting on the 622a that I'm
missing?

Here is my config line:

 __CONFIG _CP_OFF & _WDT_OFF & _HS(or XC)_OSC &
_PWRTE_ON

Thanks in advance for your consideration!
