True, but I was thinking about cases where monitor can handle some (upper  
limit) frequency, but the pll cannot produce it, and can produce some  
higher frequency (which can be the best match).

PS: As I think about it once more, I think the line

+	max_ref_div = 2*max_ref_div - min_ref_div;

is an error. I added it to ensure the algorithm wouldn't cut the range of  
ref_divs if they are all valid, but now I think it's unneeded and  
errorneous.
