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.
