Sergio,
        Just a quick note to say thank you for posting this summary of the problem,
responses, and solution. I found it very educational.

Subject: [PIC]: THANKS RE :Simulation OK but FSR won't retain data


Hello, all in the PICList:

Now, it is working fine. Was a stupid problem typing the SPBRG ...

special thanks to the people who took the time to answer:

Dan Michaels
--------------------
99:1 bet it is the software, unless you're possibly trying to use a
slow part [4 Mhz] at high frequency.

1. Maybe not saving/restoring registers correctly during interrupts,
   especially FSR.
>>>>>> Yes I'am saving them
2. Maybe mixing up FSR and INDIRECT usage somewhere.
>>>>>>>What do you mean with INDIRECT, it isn't a special register, doesn't
it ?
3. Between 10 and 14.318 timing is different, of course, so SPBRG and
   other registers/loops related to timing need fiddling.
>>>>>> Here was the problem, because I DID CHANGE the SPBRG but instead of
typing 0x5C y typed 0x52 !!!!

Mark Willis
----------------
Is this a Windowed part?  Could ambient light through the window be
modifying RAM on startup, if so?

>>>>Yes, it's is a windowed device and I often do quick tests so there is
no enough time for the EPROM cells to discharge...


Harold M Hallikainen

>>>>>  thanks for the advice of having severals FSR

thank you all !!!!!!!!
