Thank you Mr. Richard,
of course I've did a research on the forum before posting.
What I've missed, since I'm not an english speacking one, was to use some other words as keywods.
Actually "Run-Time Config" is exactly what I was looking for... but simply impossible to find insisting (as I did, shame on me) using "configuration bits" and "programmatically". Most of the results lands to how to setup the configuration bits in the code, before compile it, and not "setup configuration bits on the fly".

BTW, your suggestions was effective and I found the right post:

With all the "keyword" I've included in this message, I'm pretty sure that if somebody else is looking for the same subject, will be easier to find it.
