20.3
This table 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 this
table.

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