QUICC Engine PLL Configuration
The VCO divider (RCWL[CEVCOD]) must be set properly so that the
QUICC Engine VCO frequency is in the range of 300–600 MHz. The
QUICC Engine frequency is not restricted by the CSB and core frequencies.
The CSB, core, and QUICC Engine frequencies should be selected
according to the performance requirements.
The QUICC Engine VCO frequency is derived from the following
equations:
QUICC Engine VCO Frequency = ce_clk × VCO divider × (1 + CEPDF)
RCWL[CEPMF]
00000–00001
01001–11111
ce_clk = (primary clock input × CEPMF) ÷ (1 + CEPDF)
