 		 #118665 - if this is a survey
Responding to: ???'s previous message
Richard Erlacher said:
I'm interested in exploring the separation of the CPU from ALL the peripherals, ...
I'd guess most of the '51 implementations already have some form of a separation for SFRs. Of course, as usually, I might be fatally wrong.

Richard Erlacher said:
Whether it would be so painful to have the SFR(s) for (an) unimplemented peripheral(s) omitted and used for something else that YOU wouldn't use it.


If this is a survey and you ask me to tick one of the two options, then I tick "YES for ME it would be painful".
I'd consider a different micro. The only thing I stick to '51 is that continuity.

Oh yes, on '51 (and the other 8- and 16-bitters), I asm. I don't C. That obviously makes a difference.

How badly would this hurt ...            01/01/70 00:00

         which history?            01/01/70 00:00      
         That's my first choice ... however ...            01/01/70 00:00      
      DMA            01/01/70 00:00      
         No such plan is in the works.            01/01/70 00:00      
            DMA!            01/01/70 00:00      
               OK, but how much will you give up?            01/01/70 00:00      
                  DMA, logic and stuff...            01/01/70 00:00      
                     I think you have a different concept            01/01/70 00:00      
                        I don't understand... but...            01/01/70 00:00      
                           I'm not sure where this is headed            01/01/70 00:00      
      Cool            01/01/70 00:00

         if this is it, it is solved, if not rest            01/01/70 00:00      
   major confusion            01/01/70 00:00      
      Aye ... there's the rub...            01/01/70 00:00      
         a loud and resounding NO WAY            01/01/70 00:00      
            too late to edit            01/01/70 00:00      
               That's not what I want ... right now ...            01/01/70 00:00      
                  it DOES matter            01/01/70 00:00      
                     not in this case            01/01/70 00:00      
                        XDATA vs DATA/IDATA            01/01/70 00:00      
                           it's a work in progress, and, like many            01/01/70 00:00      
                        We seem to have come a long way            01/01/70 00:00      
                           yes, it's a mess ...            01/01/70 00:00      
                              if this is a survey            01/01/70 00:00      
                                 I'd have to agree            01/01/70 00:00      
                                    you can have your cake and eat it too.            01/01/70 00:00      
                        sure it does            01/01/70 00:00      
                           depends on memory width, doesn't it?            01/01/70 00:00      
                              go ahead, but PLEASE do not refer to the            01/01/70 00:00      
                                 I don't know what one should call it            01/01/70 00:00      
                                    I do, when it has benefits            01/01/70 00:00      
                                       I looked at them years ago            01/01/70 00:00      
                                          you are missing 'enhancements'            01/01/70 00:00      
                                             well if it uses the SFR's            01/01/70 00:00      
                                                as an example of an enhancement            01/01/70 00:00      
                                                   This is field-programmable logic.            01/01/70 00:00      
                                                      and have one more development step/uncer            01/01/70 00:00      
                                                         That's the whole point ...            01/01/70 00:00      
                           back up a bit ...            01/01/70 00:00      
                              AR7 is the annotation used by the better            01/01/70 00:00      
               Actually, that's not rational            01/01/70 00:00      
   It wouldn't bug me at all            01/01/70 00:00      
      not good enough            01/01/70 00:00      
         someone didn't read the datasheet first            01/01/70 00:00      
            that is impossible, ridiculous as well            01/01/70 00:00      
   not a thought but the fact            01/01/70 00:00      
      How to make a simple process ugly            01/01/70 00:00      
         new core            01/01/70 00:00      
            Atmel says            01/01/70 00:00      
               of course, they do            01/01/70 00:00      
               Why not just switch to another mfg?            01/01/70 00:00      
                  availability            01/01/70 00:00      
                     too bad ... how about a 68HCsomething?            01/01/70 00:00      
                     no problem            01/01/70 00:00      
                        Today Russia is            01/01/70 00:00      
      Be careful with ATMEL ...            01/01/70 00:00      
         What's with the French bashing?            01/01/70 00:00      
            French bashing            01/01/70 00:00      
               nothing wrong with french bashing            01/01/70 00:00      
                  There's nothing pressing            01/01/70 00:00      
                  You guys should be ashamed of yourselves            01/01/70 00:00      
                     Oh, LIGHTEN UP!            01/01/70 00:00      
            Probably this            01/01/70 00:00      
               Yes, that played a significant part            01/01/70 00:00      
                  I agree half the way            01/01/70 00:00      
                     Well, I'm P*ssed off!            01/01/70 00:00      
                        of course not            01/01/70 00:00      
   there are ways            01/01/70 00:00      
      Where does this fit?            01/01/70 00:00      
         with code as above you can feed a 460k U            01/01/70 00:00      
            I don't doubt that for a moment, but ...            01/01/70 00:00      
               already answered            01/01/70 00:00      
                  they're cleared independently, right?            01/01/70 00:00      
                  you get to the ISR, how do you know why?            01/01/70 00:00      
                     isn't that TI and RI            01/01/70 00:00      
                        I'm puzzled too            01/01/70 00:00      
                     you have two flags            01/01/70 00:00      
                        and so what?            01/01/70 00:00      
                           That would cause a problem.            01/01/70 00:00      
                              Richard, sleep on it            01/01/70 00:00      
                                 It's exactly how Moto does it            01/01/70 00:00      
                                 Maybe not ...            01/01/70 00:00      
                                    JBC            01/01/70 00:00      
                                       it's not clear yet            01/01/70 00:00      
                                    What is the difference, they take the sa            01/01/70 00:00      
                                 to Richard            01/01/70 00:00      
                                    Thanks, I'll give it a look            01/01/70 00:00      
   you get to the ISR, how do you know why?            01/01/70 00:00      
      don't RI and TI tell you?            01/01/70 00:00
