Clocking
19.1
The system PLL is controlled by the RCWL[SPMF] parameter.
encodings for the system PLL.
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).
78
The DDR data rate is 2× the DDR memory bus frequency.
The local bus frequency is ½, ¼, or 1/8 of the lbiu_clk frequency (depending on LCCR[CLKDIV]) which is in turn 1× or 2× the
csb_clk frequency (depending on RCWL[LBIUCM]).
