1 _{The frequency depends on the value of PCI_MODCK. If PCI_MODCK is high (logic ‘1’), the PCI frequency is}
divided by 2 (33 instead of 66 MHz, etc.) and the CPM multiplication factor is multiplied by 2. Refer to Table 15.
2 _{Input clock frequency is given only for the purpose of reference. User should set MODCK_H–MODCK_L so that}
the resulting configuration does not exceed the frequency rating of the user’s part.
3 _{Core frequency = (60x bus frequency)(core multiplication factor)}
4 _{Bus frequency = CPM frequency/bus division factor}
5 _{In this mode, PCI_MODCK must be “1”.}
