hi, all :)

after i build my program in assembly using MPLAB, i faced this error massage ( Argument out of range (not a valid config register address) )

this is the configuration bits initializations
Code: 
__CONFIG _CP_OFF & _WDT_OFF & _BODEN_ON & _PWRTE_ON & _XT_OSC & _WRT_ENABLE_OFF & _LVP_ON & _CPD_OFF


i couldn't fix this error. So, what is the solution for this error???? :confused::confused:

hi, Nigel

this is all the program

Code: 
list      p=16f873            ; list directive to define processor
#include <p16f873.inc>        ; processor specific variable definitions
__CONFIG _CP_OFF & _WDT_OFF & _BODEN_OFF & _PWRTE_OFF & _XT_OSC & _WRT_ENABLE_OFF & _LVP_OFF & _CPD_OFF

For a start delete all the spurious equates at the start of the program, that's what the include file is for.

Do you need the # on the include?, I always do it like:

Code: 
	include "P16F873.inc"
 
hi,

i traid to delete all spurious equates at the start of the program, but the error still not solved...
 
You had instructions in the first column, as the error codes would have told you, I've tabbed them across now.

Try this

Code: 
	list      p=16f873            ; list directive to define processor
	#include <p16f873.inc>        ; processor specific variable definitions
