Oh... I think I understand what you're saying.... the chip has a calibration that was wiped out when I UV-ed it (I'm using a window-ed chip)... so I need to re-program it. Correct?

Add the line shown in bold below.
Quote:

#include <12C672.h>
#fuses INTRC_IO, NOWDT, NOPROTECT, PUT, NOMCLR
#use delay(clock=4000000)

#rom 0x7FF = {0x3400}


This will put a "RETLW 00" instruction at address 0x7FF, which should
fix the problem.
