Hello...
I'm using an 18F1320 and have written code that once worked...
The code appears to download fine ( as indicated by the meLabs serial programmer...)... but now it does not execute...
I probed around on the circuit PCB and found that the 4MHZ xtal clock was not running...
I have the DEFINE OSC 4 in the code... and...
I found the CONFIG1H register and set it for the XT OSC mode... no help...

What am I missing to set up the 18F1320 to run on the 4MHZ XT clock?
with out having to depend on the meLabs serial programmer...

thanks
Dave
