79 / 99 page  MPC8347EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 12 Freescale Semiconductor 79 Clocking 19.1 System PLL Configuration The system PLL is controlled by the RCWL[SPMF] parameter. Table 60 shows the multiplication factor encodings for the system PLL. As described in Section 19, “Clocking,” the LBIUCM, DDRCM, and SPMF parameters in the reset 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). Table 61 3 The DDR data rate is 2× the DDR memory bus frequency. 4 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]).
