#129049 - Really?
Responding to: ???'s previous message
You don't think it looks like a "Stuck-At" address problem, then?

[Update]
see: http://www.8052.com/forum/read.phtml?id=128888
[/Update]

As ever, of course, this could easily be tested by simply running the code in a simulator:
  • If the simulator produces the same results, then the error does lie in the code;
  • If the simulator does not produce the same results, then the problem most likely lies in the Hardware.

                it's the HW then            01/01/70 00:00      
             Yes, it looks like that.            01/01/70 00:00      
                Oh no it doesn't!            01/01/70 00:00      
                   first of all, let me be clear ...            01/01/70 00:00
