Core PLL Configuration
RCWLR[COREPLL] selects the ratio between the internal coherent system bus clock (csb_clk) and the
e300 core clock (core_clk). Table 79 shows the encodings for RCWLR[COREPLL]. COREPLL values
that are not listed in Table 79 should be considered as reserved.
NOTE
Core VCO frequency = core frequency
× VCO divider
VCO divider has to be set properly so that the core VCO frequency is in the
range of 800–1600 MHz.

Notes:
1. CFG_CLKIN_DIV doubles csb_clk if set high.
2. CLKIN is the input clock in host mode; PCI_CLK is the input clock in agent mode.
