Clock Configuration Modes
3.2
PCI Mode
The MPC8265 and the MPC8266 have three clocking modes: local, PCI host, and PCI agent. The clocking
mode is set according to three input pins—PCI_MODE, PCI_CFG[0], PCI_MODCK—as shown in
In addition, note the following:
NOTE: PCI_MODCK
In PCI mode only, PCI_MODCK comes from the LGPL5 pin and
MODCK_H[0–3] comes from {LGPL0, LGPL1, LGPL2, LGPL3}.
NOTE: Tval (Output Hold)
The minimum Tval = 2 when PCI_MODCK = 1, and the minimum Tval = 1
when PCI_MODCK = 0. Therefore, designers should use clock
configurations that fit this condition to achieve PCI-compliant AC timing.
NOTE
Clock configurations change only after POR is asserted.

1 Because of speed dependencies, not all of the possible configurations in Table 14 are applicable.
2 The user should choose the input clock frequency and the multiplication factors such that the frequency of the CPU
is equal to or greater than 150 MHz and the CPM ranges between 66–233 MHz.
3 Input clock frequency is given only for the purpose of reference. The user should set MODCK_H–MODCK_L so that
the resulting configuration does not exceed the frequency rating of the user’s part.
