This table provides the operating frequencies for the MPC8313E TEPBGAII under recommended
operating conditions (see Table 2).

System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. This table shows the multiplication factor
encodings for the system PLL.

Note:
1. The SYS_CLK_IN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen
such that the resulting csb_clk, MCK, LCLK[0:1], and core_clk frequencies do not exceed their
respective maximum or minimum operating frequencies. The value of SCCR[ENCCM] and
SCCR[USBDRCM] must be programmed such that the maximum internal operating frequency of
the security core and USB modules do not exceed their respective value listed in this table.
2. The DDR data rate is 2x the DDR memory bus frequency.
3. The local bus frequency is 1/2, 1/4, or 1/8 of the lbc_clk frequency (depending on
LCRR[CLKDIV]), which is in turn, 1x or 2x the csb_clk frequency (depending on RCWL[LBCM]).
