Hello,

I have a question concerning the way a controller interpreted a hex file
to explain have a look at following little example:

1 $mod52
2
2000 3 org 2000H
2000 52454144 4 DB 'READY'
2004 59
5
2020 6 org 2020H
2020 7400 7 mov A,#00H
2022 00 8 begin: NOP
2023 00 9 NOP
2024 022027 10 jmp einde
11 ;code of the program...
2027 00 12 einde: NOP
13 end

The Hex translation of this (with asm51.exe) is the following):

:05 2000 00 524541445966
:08 2020 00 7400000002202700FB
:00 0000 01 FF

My Question is how can the controller now when he interpretes this code that for example
the code 52 is the letter R and not the command: ANL Daddr,A .How does he make the switch
to know if it is the command or the data character.
I don't see in the generated hex-code a difference.

Greetings and looking forward to some reactions...
