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

CFG_SYS_CLKIN_DIV
CFG_SYS_CLKIN_DIV
CFG_SYS_CLKIN_DIV select the ratio between SYS_CLKIN and PCI_SYNC_OUT.
SYS_CLKIN is the input clock in host mode; PCI_CLK is the input clock in agent mode.
In the Host mode it does not matter if the value is High or Low.
CFG_SYS_CLKIN_DIV doubles csb_clk if set low.
SYS_CLKIN is the input clock in host mode; PCI_CLK is the input clock in agent mode.
