Notes:
1.Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK
2.)The minimum e500 core frequency is based on the minimum platform frequency of 200 MHz.
3.)The 1.0 GHz core frequency is based on a 1.3 V VDD supply voltage.
Memory bus frequency
Notes:
1.Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK
2.The memory bus speed is half of the DDR data rate, hence, half of the platform clock frequency.
3.)The 1.0 GHz core frequency is based on a 1.3 V VDD supply voltage.
