Clock Configuration Modes
3.2.2
PCI Agent Mode
The frequencies listed in Table 18 and Table 19 are for the purpose of illustration only. Users must select
a mode and input bus frequency so that the resulting configuration does not exceed the frequency rating
of the user’s device.

1 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 15.
3 In this mode, PCI_MODCK must be “0”.
