 		 #113083 - Requirements, a most important variable
Responding to: ???'s previous message
You've hit on the most important point, Peter, and that's the REQUIREMENTS. If a device doesn't need more memory, or any other resource, than what's provided internally, then no external decoding is required. However, if one has an 8031, for example, it DOES require external memory and might well benefit from other external resources.

The OP asked about how to decode the memory address, but the first thing he got, from you, in this case, instead of an answer to his question, was an implied criticism for not using a part that didn't require it. While this is a reasonable thing to wonder, wouldn't it be more thoughtful to answer his question? That question didn't even specifically ask about 805x core MCU's, but asked the question in a way applicable to nearly any sort of microcontroller/microprocessor device.

Why not answer the question asked rather than attacking the individual for asking it?

How to decoder the memory address?            01/01/70 00:00      
   decoding already inside            01/01/70 00:00      
      That's not fair!            01/01/70 00:00      
         ???            01/01/70 00:00

               why Flash esoteric ???            01/01/70 00:00      
                  So ... where's the decoding?            01/01/70 00:00      
                     decoding in practice            01/01/70 00:00      
                        This is not a personal attack, Peter            01/01/70 00:00      
                           actually            01/01/70 00:00

                                  Sorry Richard I was a little more            01/01/70 00:00      
                              there is an ignore function available            01/01/70 00:00      
                                 that is how I currently do it            01/01/70 00:00      
                                    drop the flat mode, go threaded            01/01/70 00:00      
   There's a way, once you've decided            01/01/70 00:00

               How many address buses do you see?            01/01/70 00:00      
                  On the busses            01/01/70 00:00      
                     The only purpose was...            01/01/70 00:00
