 		 #135180 - ICE or Eprom Emulator ?
Responding to: ???'s previous message
The microcontroller is a Philips 80C52, which is being controller by an emulator (Micetek EasyPack 51). I am not sure but I suppose the problem is not related to the emulator, since it is designed to use all 4 ports, and the software too.


I could not find much info about MICETEK emulators.
If it's an Eprom Emulator it will use P0 and P2 to connect to the 80C52. If this is the case you cannot use these ports for I/O.
If you have an ICE (In Circuit Emulator) It should plug into your target board where the 80C52 would normally go, with this you should be able to access p0 and P1.

   How do you detect that it's ignored?            01/01/70 00:00

               Check the datasheet!            01/01/70 00:00

                        I think it does have internal ROM            01/01/70 00:00

            It is an in-circuit emulator            01/01/70 00:00      
   my assumption            01/01/70 00:00      
      I'm afraid it can't be            01/01/70 00:00      
         There's a special "once" mode ... for emulators            01/01/70 00:00      
         try this            01/01/70 00:00

               My guess            01/01/70 00:00      
                  Read the datasheets and read the posts, Mike            01/01/70 00:00      
            How is all this supposed to help?            01/01/70 00:00      
               It has code space...            01/01/70 00:00      
                  Where did you get that nonsense, Mike?            01/01/70 00:00      
   My conclusion:            01/01/70 00:00      
      What has it to do with the original question?            01/01/70 00:00      
   I do not know your emulator, but            01/01/70 00:00      
      My conclusion (and thanks for everyone)            01/01/70 00:00      
         then why not say so            01/01/70 00:00
