Freescale Semiconductor
Clocking
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 400–800 MHz.

QUICC Engine PLL Configuration
The QUICC Engine PLL is controlled by the RCWL[CEPMF] and RCWL[CEPDF] parameters. Table 58
shows the multiplication factor encodings for the QUICC Engine PLL.
