Responding to: ???'s previous message

The important thing here is that when you start programming, you do a lot of mistakes.

And what you really don't want in such a situation is the added complication, when you see a problem, of not being certain whether it's your code or PROM programmer - or both!

Yes, a badly erased EPROM, or a an EPROM with the cells programmed slightly too short time (or with too low programming voltage) will really destroy an otherwise good day. To have a EPROM that may pass the checksum test directly when programmed, but not 30 minutes later...

When the charge in an EPROM memory cell is close to the border between a zero and a one, you can get a situation where the temperature changes the bit, so you get a random performance from the program. And looking at the source code will not tell anything about the strange behaviour.

   Eh??            01/01/70 00:00      
   Huh?            01/01/70 00:00      
   There's the totally free and unrestricted ASEM-51            01/01/70 00:00      
   if you are just starting ....            01/01/70 00:00      
      Look Here            01/01/70 00:00      
         There's only one catch            01/01/70 00:00      
            actually, they do.            01/01/70 00:00      
               but they deny it            01/01/70 00:00      
                  why would it be?            01/01/70 00:00      
                     Yes, they sell chips, but they're of no use without support            01/01/70 00:00      
                        the "native language of a chip"            01/01/70 00:00      
                        Assembler is *not* the native language of the chip!            01/01/70 00:00      
                  They make the silicon - not the tools            01/01/70 00:00      
            Don't see manufacturer "supporting" assembler or C            01/01/70 00:00      
               I totally agree            01/01/70 00:00      
                  while I'm inclined to agree ...            01/01/70 00:00      
                     Rubbish            01/01/70 00:00      
                        If only that were relevant            01/01/70 00:00      
                           Nonsense            01/01/70 00:00      
                              remember what the O/P wanted            01/01/70 00:00      
                                 on-chip debug is superior regardless of language            01/01/70 00:00      
                                    and the one on that EVK is one of them            01/01/70 00:00      
                                       there is no 'THE" evk            01/01/70 00:00      
                                 It is not at all clear what the OP actually wanted!            01/01/70 00:00      
                                    Vague?            01/01/70 00:00      
                                       Yes - vague!            01/01/70 00:00      
                                          Aren't you overreaching?            01/01/70 00:00      
                                             Don't upgrade murky into prime            01/01/70 00:00      
                                       then answer that            01/01/70 00:00      
                                          It's clear that some of you guys have your heads wedged            01/01/70 00:00      
                                             Too many unknowns            01/01/70 00:00      
                                                The first question was clear enough wasn't it?            01/01/70 00:00      
                                                   Easy answers can be so very, very wrong            01/01/70 00:00      
                                                      That's not the case here ...            01/01/70 00:00      
                                             throwing good money after bad            01/01/70 00:00      
                           Total Rubbish            01/01/70 00:00      
                              Let me add...            01/01/70 00:00      
                                 More SiLabs Asm Support            01/01/70 00:00      
                                    I second the motion            01/01/70 00:00      
                                    Hopefully that will make it easier            01/01/70 00:00      
                                       Cease and Desist            01/01/70 00:00      
                                       conversations with the SiLabs folks            01/01/70 00:00      
                                          That's what I'd expect.            01/01/70 00:00      
                                             That's not what yo said            01/01/70 00:00      
                                                there's a reason            01/01/70 00:00      
                                                   Maybe the SiLabs guy(s) took a similar view...?            01/01/70 00:00      
                                             since when is "C for a '51" not "805x code"            01/01/70 00:00      
                                                'C' doesn't look like 805x code ... isn't that the point?            01/01/70 00:00      
                                                   the point, the definition            01/01/70 00:00      
                                                      The only thing the 805x core executes is binary            01/01/70 00:00      
                                                         just like            01/01/70 00:00      
                                                            are you saying it's not relevant?            01/01/70 00:00      
                                                               "the bible" is as relevant as ever.            01/01/70 00:00      
                                                                  The O/P has to start somewhere            01/01/70 00:00      
                                                                     not for most            01/01/70 00:00      
                                                                        bad assumption ...            01/01/70 00:00      
                                                   What's so hard            01/01/70 00:00      
                                                      nobody said it was hard            01/01/70 00:00      
                                                         wrong premise            01/01/70 00:00      
                                                            He specifically asked for an assembler            01/01/70 00:00      
                                                               well,            01/01/70 00:00      
                                                                  Do you want to be "second-guessed" all the time?            01/01/70 00:00      
                                                                     what is wrong with this analogy ....            01/01/70 00:00      
                                                                        He probably knows but can't explain it            01/01/70 00:00      
                                                                           that's why            01/01/70 00:00      
                                                                              don't go overboard, Erik!            01/01/70 00:00      
                                                                                 OK, I understand            01/01/70 00:00      
                                                                                    That's not what I meant ...            01/01/70 00:00      
                                                                                       no, he did not            01/01/70 00:00      
                                                                                          I don't disagree ...            01/01/70 00:00      
                                             sequence            01/01/70 00:00      
                                                You're right!            01/01/70 00:00      
                              that's not what the O/P wanted, though            01/01/70 00:00      
                                 trying to get investors for a buggy-whip factory            01/01/70 00:00      
                                    Isn't this about what the O/P wanted?            01/01/70 00:00      
                                       you are the champ in ...            01/01/70 00:00      
                                          I was mistaken ... it's SPI that they provided            01/01/70 00:00      
                                       Who cares about the OP?            01/01/70 00:00      
                                          Based on the O/P's query ...            01/01/70 00:00      
                                             You're the one reading-in requirements!            01/01/70 00:00      
                                                question as asked often not really one to answer!            01/01/70 00:00      
                                                   Why assume he's wrong?            01/01/70 00:00      
                                                      whay assume he is right?            01/01/70 00:00
