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 12
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”.
