RCWL[COREPLL] selects the ratio between the internal coherent system bus clock (csb_clk) and the e300
core clock (core_clk). This table shows the encodings for RCWL[COREPLL]. COREPLL values that are
not listed in this table should be considered as reserved.

Note:
For any core_clk:csb_clk ratios, the core_clk must not exceed its maximum operating frequency of 400 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.
