Clock Configuration Modes
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 Rev0.1 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 Table 17 shows, 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 60x and local bus frequency. Identical to CLKIN.
5 CPM multiplication factor = CPM clock/bus clock
6 CPU multiplication factor = Core PLL multiplication factor
