PCI Agent Mode
Table 18 and Table 19 show configurations for PCI agent mode. The frequency values listed 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. Note that in PCI agent mode the
input clock is PCI clock.
