Clocking
As described in
configuration word low and the CFG_CLKIN_DIV configuration input signal select the ratio between the
primary clock input (CLKIN or PCI_CLK) and the internal coherent system bus clock (csb_clk).
shows the expected frequency values for the CSB frequency for select csb_clk to CLKIN/PCI_SYNC_IN
ratios.
