The “l(fā)ow” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency
guarantees the required minimum CPU operating frequency. Minimum CPU frequency is determined by the clock
mode. For modes with a CPU multiplication factor
≤
3, the minimum CPU frequency is 125 MHz or 150 MHz, as
shown in the table. For modes with a CPU multiplication factor
≥
3.5, the minimum CPU frequency is 250 MHz.
The “high” values 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.
2
PCI_MODCK determines the PCI clock frequency range. Refer to Table 17 for higher range configurations.
3
MODCK_H = hard reset configuration word [28–31] (refer to Section 5.4 in the
MPC8260 User’s Manual
).
MODCK[1-3] = three hardware configuration pins.
4
CPM multiplication factor = CPM clock/bus clock
5
CPU multiplication factor = Core PLL multiplication factor
