e500 Core PLL Ratio
Table 78 describes the clock ratio between the e500 core complex bus (CCB) and the e500 core clock. This
ratio is determined by the binary value of LBCTL, LALE, and LGPL2 at power up, as shown in Table 78.

Sysclk to Platform Frequency Options
Table 79 shows the expected frequency values for the platform frequency when using a CCB clock to
SYSCLK ratio in comparison to the memory bus clock speed.

Note: Due to errata Gen 13 the max sys clk frequency should not exceed 100 MHz if the core clk frequency is below
1200 MHz.
