From: Scott Stephens | |I just read the note on Eric Smith's PIC Page |http://www.spies.com/~eric/pic/ |mentioning a problem with Interrupts occuring during a table read |operation. AN556, page 5-3, bottom, under bold heading Iterrupts |states that "...if the interrupt occurs just before the "movwf pcl" |instruction...On return from interrupt ,the program will go to the |intended offset of the table +1...a very undesirable result, so |interrupts must be disabled during a table read.." | |Eric states on his page that at a seminar the Microchip rep's said |this wasn't a problem. | |Anyone aware of this, will MPSIM handle is the way a 16C84 will? Scott, I was one of several who found conflicting results and suspected that the problem didn't actually exist. A couple of people at Microchip, including the author of AN556, have since told me that this is indeed the case -- the problem does not exist, nor has it ever existed. My WWW connection is not working right now, but if someone were to send me Eric Smith's email address, I would be happy to forward to him my email archive on this problem, including the note from D'Souza. For that, matter, if anyone else wants a copy, you're welcome to it, just send me an email address.
