hello,

I have written a very simple assembly language programme, but I am unsure about 1 thing. I need to find out the 16 bit machine code instruction stored at 0x1c. I have tried microchips website but it does not make much sense, this is the program below

; mptest.asm

title "mptest.asm"
list p=18f452, f=inhx32
#include <p18f452.inc>

storea equ h'00'
storeb equ h'01'
storec equ h'02'

TEN equ d'10'
ONE equ d'01'

org 0x00
goto start

org 0x1C

start
movlw TEN
movwf storea
incf storea, f
movf storea, w
movwf storeb
movlw ONE
movwf storec
decf storec, w
loop
goto loop

end

Thanks for your help

'org' is a compiler directive that tells the assembler where the next instruction of code should be. So the 16 bit instruction at 0x1C will be the first instruction after the 'org 0x1C' directive.
