The MPC8245 internal PLLs are configured by the PLL_CFG[0:4] signals. For a given PCI_SYNC_IN (PCI bus)
frequency, the PLL configuration signals set both the peripheral logic/memory bus PLL (VCO) frequency of
operation for the PCI-to-memory frequency multiplying and the MPC603e CPU PLL (VCO) frequency of operation
for memory-to-CPU frequency multiplying. The PLL configurations for the 400- and 466-MHz parts are shown in
