27 / 50 page  MPC8260A PowerQUICC™ II Integrated Communications Processor Hardware Specifications, Rev. 2.0 Freescale Semiconductor 27 Clock Configuration Modes 3.2.1 PCI Host Mode The frequencies listed in Table 16 and Table 17 are for the purpose of illustration only. Users must select a mode and input bus frequency so that the resulting configuration does not exceed the frequency rating of the user’s device. I Table 17 describes all possible clock configurations when using the MPC8265’s or the MPC8266’s internal PCI bridge in host mode. Table 16. Clock Default Configurations in PCI Host Mode (MODCK_HI = 0000) MODCK[1–3]1 1 Assumes MODCK_HI = 0000. Input Clock Frequency (Bus) CPM Multiplication Factor CPM Frequency Core Multiplication Factor Core Frequency PCI Division Factor2 2 The frequency depends on the value of PCI_MODCK. If PCI_MODCK is high (logic ‘1’), the PCI frequency is divided by 2 (33 instead of 66 MHz, etc.) Refer to Table 15.
