between the e500 core clock and the e500 core complex bus (CCB) clock. There is no default value for
this PLL ratio; these signals must be pulled to the desired values. Note that the values latched on these
signals during POR are accessible through the memory-mapped PORPLLSR, as described in
Section 19.4.1.1, “POR PLL Status Register (PORPLLSR),”
