RCWL[COREPLL] selects the ratio between the internal coherent system bus clock (csb_clk) and the e300
core clock (core_clk).

For core_clk:csb_clk ratios of 2.5:1 and 3:1, the core_clk must not exceed its maximum operating frequency of
333 MHz.
Core VCO frequency = core frequency × VCO divider. Note that VCO divider has to be set properly so that the core
VCO frequency is in the range of 400–800 MHz.

Core VCO frequency = core frequency × VCO divider. The VCO divider,
which is determined by RCWLR[COREPLL], must be set properly so that
the core VCO frequency is in the range of 400–800 MHz.
