NOTE
Core VCO frequency = Core frequency × VCO divider. The 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.

QUICC Engine Block PLL Configuration
The QUICC
Engine block PLL is controlled by the RCWL[CEPMF], RCWL[CEPDF], and
RCWL[CEVCOD] parameters.
Table 74
shows the multiplication factor encodings for the QUICC Engine
block PLL.
