1 _{Assumes MODCK_HI = 0000.}
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.) and the CPM multiplication factor is multiplied by 2. Refer to Table 15.
3 _{Core frequency = (60x bus frequency)(core multiplication factor)}
4 _{Bus frequency = CPM frequency/bus division factor}
Table 19 describes all possible clock configurations when using the MPC8265 or the MPC8266’s internal
PCI bridge in agent mode.
