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
2 Input clock frequency is given only for the purpose of reference. User should set MODCK_H–MODCK_L so
that the resulting conguration 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”.
