PLL Configurations
The 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 are shown in Table 17
