Hi,
I have been using GPSim at the start for simulating (F877) and also
used the 7-segment example code to study the behaviour of the 7-segment.
Just tried to change the code to the F690.
I used reading the specification a quite a bit more and at last this
newbie understood that even the Program Counter is 13bit in PIC16F690
( and in others as well ), the last 8-bits are able to be used for
jumping etc.. (of course, stupid me). So the lookup table I created to
the other file was out of the 8bit space and caused all these problems.
After I specifically told to the asm to put the code to different memory
location, everything started to work.
