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).
Freescale Semiconductor
DDR1/DDR2 memory bus frequency (MCLK)
Local bus frequency (LCLK n )
PCI input frequency (CLKIN or PCI_CLK)
The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting csb_clk , MCLK,
LCLK[0:2], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies.
The DDR1/DDR2 data rate is 2× the DDR1/DDR2 memory bus frequency.
The local bus frequency is 1/2, 1/4, or 1/8 of the lb_clk frequency (depending on LCRR[CLKDIV]) which is in turn 1× or 2× the
csb_clk frequency (depending on RCWL[LBCM]).

System PLL Configuration
System PLL VCO frequency = 2 × (CSB frequency) × (System PLL VCO
divider).
The VCO divider needs to be set properly so that the System PLL VCO
frequency is in the range of 300–600 MHz.
