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.
2
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.). Refer to Table 14.
3
In this mode, PCI_MODCK must be “0”.
