The frequency depends on the value of PCI_MODCK. If PCI_MODCK is high (logic ‘1’), the PCI frequency
Input clock frequency is given only for the purpose of reference. User should set MODCK_H–MODCK_L so
Core frequency = (60x bus frequency)(core multiplication factor)
Bus frequency = CPM frequency / bus division factor
In this mode, PCI_MODCK must be “1”.
is divided by 2 (33 instead of 66 MHz, etc.) and the CPM multiplication factor is multiplied by 2. Refer to
Table 14.
that the resulting configuration does not exceed the frequency rating of the user’s part.
