Do you think this kind of information could be found by > searching keywords ? I don't think it is feasible (realistic) to be automated because of the large variety of options. The problem is with the 18Fs. Say you want for all 18Fs to have the bits set for internal oscillator at 4 MHz frequency. There are several types of oscillators even multiple internal oscillators, different default speeds, several PLL options, several CPU frequency dividers, and maybe more. I have not investigated this in details (otherwise I wouldn't have a problem anymore!), but I wouldn't be surprised if for the about 200 18Fs there are 50 different combinations. It might be faster to read the datasets then find a method that covers all combinations. And it is also a one-off excercise: once done (and documented) it is only needed for new PICS. I think you can spend your time better.
