39 / 58 page  MPC8241 Integrated Processor Hardware Specifications, Rev. 10 Freescale Semiconductor 39 PLL Configuration 6 PLL Configuration The PLL_CFG[0:4] are configured by the internal PLLs. For a specific 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 and Table 18. Table 17.
