Clocking
As described in
configuration word low and the CFG_CLKIN_DIV configuration input signal select the ratio between the
primary clock input (SYS_CLK_IN or PCI_SYNC_IN) and the internal coherent system bus clock
(csb_clk).
SYS_CLK_IN/PCI_SYNC_IN ratios.

CFG_CLKIN_DIV
CFG_CLKIN_DIV select the ratio between SYS_CLK_IN and PCI_SYNC_OUT.
SYS_CLK_IN is the input clock in host mode; PCI_CLK is the input clock in agent mode.
