“Low” 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 166 MHz. The minimum CPM frequency
is 133 MHz.
For modes with a CPU multiplication factor
≥
3.5, the minimum CPU frequency is 250 MHz. The minimum CPM
frequency is as shown in the table.
“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
As shown in Table 14, PCI_MODCK determines the PCI clock frequency range. Refer to Table 19 for lower
configurations.
3
MODCK_H = hard reset configuration word [28–31]. MODCK[1-3] = three hardware configuration pins.
4
CPM multiplication factor = CPM clock/PCI clock
5
CPU multiplication factor = Core PLL multiplication factor
