Description
***********



.. code-block:: none

   Nordic Auxiliary PLL (Phase Locked Loop)

   The output frequency (f_out) of the auxiliary PLL is calculated as follows:

     f_out = ((R + A * 2^(-16)) * f_src) / B

   where:

     - A: nordic,frequency
     - B: nordic,outdiv
     - R: nordic,range (3=low, 4=mid, 5=high, 6=statichigh)
     - f_src: Source frequency, given by clocks

                wake up the system.
