I am using MPLAB v8.6, XC8 v1.1. (free mode)., ICD3 and PICDEM2.
Although I can compile programs and flash them onto my PIC18F4520 - (they all seem to work as expected), I get a couple of advisory/warnings during compilation:-
Advisory Employing 18F4520 errata work-arounds:
Advisory * Corrupted fast interrupt shadow registers
Warning  ; . Omniscient Code Generation not available in Free mode
Warning  ; . missing configuration setting for config word 0x300003, using default
Does anyone know why I get these and if there is anyway to rectify them?
Thanks in advance.
