Clock Configuration Modes
7.2
PCI Agent Mode
These tables 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.
6 CPM_CLK/PCI_CLK ratio. When PCI_MODCK = 1, the ratio of CPM_CLK/PCI_CLK should be calculated from
PCIDF as follows:
PCIDF = 3 > CPM_CLK/PCI_CLK = 4
PCIDF = 5 > CPM_CLK/PCI_CLK = 6
PCIDF = 7 > CPM_CLK/PCI_CLK = 8
PCIDF = 9 > CPM_CLK/PCI_CLK = 5
PCIDF = B > CPM_CLK/PCI_CLK = 6
