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.

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.
