Use a PLL as a fast counter

My question is if I have any access (can be a slow access) to the value of the
N-div register (integer mode).
I am asking it because it seems to me as the most economical way to implement a
very high speed counter (which is needed in order to measure RF frequencies).

Specifically, I refer to the HMC70x family (x = 1 to 4).

I am aware that such a register access is not explicitly mentioned in datasheets, but I explore the possibility that an access exists and may not published....
