Clock Configuration Modes
1.3.2.2
PCI Agent Mode
The frequencies listed in Table 17 and Table 18 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.
Table 18 describes all possible clock configurations when using the MPC8265 or the MPC8266’s internal
PCI bridge in agent mode.

Assumes MODCK_HI = 0000.

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 14.

Core frequency = (60x bus frequency)(core multiplication factor)

Bus frequency = CPM frequency / bus division factor
