    Notes:
    1. Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK
    frequency, e500 (core) frequency, and CCB frequency do not exceed their respective maximum or minimum operating
    2.)The minimum e500 core frequency is based on the minimum platform frequency of 333 MHz.

    SYSCLK frequency, e500 (core) frequency, and CCB clock frequency do not exceed their respective maximum or minimum
    settings.
    2. The memory bus speed is half of the DDR/DDR2 data rate, hence, half of the platform clock frequency.
