1 The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency in a table entry
guarantees only the required minimum CPU operating frequency. 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 violate the frequency rating of the user’s
device. The minimum CPM frequency is 120 MHz. Minimum CPU frequency is determined by the clock mode. For modes with
a CPU multiplication factor <= 3, the minimum CPU frequency is 150 MHz for commercial temperature devices and 175 MHz
for extended temperature devices. For modes with a CPU multiplication factor >= 3.5: for Rev 0.1 the minimum CPU frequency
is 250 MHz; for Rev A or later the minimum CPU frequency is 150 MHz for commercial temperature devices and 175 MHz for
extended temperature devices.
2 As shown in Table 17, PCI_MODCK determines the PCI clock frequency range. See Table 20 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
