Core VCO frequency = Core frequency × VCO divider. VCO divider
(RCWL[COREPLL[0:1]]) must be set properly so that the core VCO
frequency is in the range of 800–1800 MHz. Having a core frequency below
the CSB frequency is not a possible option because the core frequency must
be equal to or greater than the CSB frequency.
