Clock Conguration Modes
1.3.2
PCI Mode
This section pertains to the MPC8265A and the MPC8266A only.
In PCI mode only, MODCK_HI[0:3] and PCI_MODCK come from the following external pins:
PCI_MODCK = LGPL5
MODCK_HI[0:3] = {LGPL0,LGPL1,LGPL2,LGPL3}
NOTE
The minimum Tval = 2 when PCI_MODCK = 1 and minimum Tval = 1
when PCI_MODCK = 0; therefore, board designers should use clock
congurations that t this condition to achieve PCI-compliant AC timing.

1 Because of speed dependencies, not all of the possible congurations in Table 15 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 than150 MHz and the CPM ranges between 66–233 MHz.
3 Input clock frequency is given only for the purpose of reference. User should set MODCK_H–MODCK_L so that
the resulting conguration does not exceed the frequency rating of the user’s part.
Example. If a part is rated at 266 MHz CPU, 200 MHz CPM, and 66 MHz bus, any of the following are possible
(note that the three input clock frequencies are only three of many possible input clock frequencies):
1. 66 MHz input clock and MODCK_H–MODCK_L[0111–101] (with a core multiplication factor of 4 and a CPM
multiplication factor of 3). The resulting conguration equals the part’s maximum possible frequencies of
266 MHz CPU, 200 MHz CPM, and 66 MHz bus.
2. 50 MHz input clock and MODCK_H–MODCK_L[0111–101] to achieve a conguration of 200 MHz CPU,
150 MHz CPM, and 50 MHz bus.
3. 40 MHz input clock and MODCK_H–MODCK_L[0010–011] to achieve a conguration of 200 MHz CPU,
160 MHz CPM, and 40 MHz bus.
Note that with each example, any one of several values for MODCK_H–MODCK_L could possibly be used as
long as the resulting conguration does not exceed the part’s rating.
4 At this mode the CPU PLL is bypassed (the CPU frequency equals the bus frequency).
