 		 #128890 - Stuck
Responding to: ???'s previous message

i don't understand that when you are saying that SRAM addresses are stuck, how it happens..

That would be a hardware fault: either the line is short-circuited to GND or VCC, or the line is disconnected and so "floats" to to '1' (or '0')

                     i have seen your profile            01/01/70 00:00      
                        It seems to have changed            01/01/70 00:00

                           Erik by god it is recently changed!            01/01/70 00:00      
   I think Neil is asking            01/01/70 00:00      
   Isn't this a 'C' problem rather than a RAM problem            01/01/70 00:00      
      Really?            01/01/70 00:00      
         code tested at simulator            01/01/70 00:00      
            So it's a hardware fault            01/01/70 00:00      
               Hardware tested            01/01/70 00:00      
                  answer to "why":            01/01/70 00:00      
                     but dont forget to put pull ups its port 0!            01/01/70 00:00      
                        for the test - yes, sure, sorry, I forgot            01/01/70 00:00      
                  "Hardware tested" and who gives a hoot            01/01/70 00:00      
                  Tested?!            01/01/70 00:00      
            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      
                  not just stuck-at            01/01/70 00:00      
                     Good point!            01/01/70 00:00      
                        Let's give him credit ...            01/01/70 00:00
