The RCWL[CEVCOD] denotes the QUICC Engine Block PLL VCO internal frequency as shown in
Table
The QUICC Engine block VCO frequency is derived from the following equations:
Freescale Semiconductor
73.
ce_clk = (primary clock input × CEPMF) ÷ (1 + CEPDF)
QE VCO Frequency = ce_clk × VCO divider × (1 + CEPDF)
MPC8358E PowerQUICC II Pro Processor Revision 2.1 PBGA Silicon Hardware Specifications, Rev. 3
The VCO divider (RCWL[CEVCOD]) must be set properly so that the
QUICC Engine block VCO frequency is in the range of 600–1400 MHz.
The QUICC Engine block frequency is not restricted by the CSB and core
frequencies. The CSB, core, and QUICC Engine block frequencies should
be selected according to the performance requirements.
