I wonder if I did something wrong, or maybe this is a bug in mplab.
I was using the simulator to exercise a program for 16F84, running
at 4 Mhz. I had some Bit manipulations of the data in the last
memory location of the pic (0x4F). I noticed that one of the bits
would not set when the bcf instruction executed. I changed the
location to 0x4E, and it worked fine. This is version 5 which I got
from the Mchip website a few months ago. Maybe I did something
to make it behave this way, but I sure cant figure it out!
