Clock Ranges
Table 53 provides the clocking specifications for the processor core.
Table 54 provides the clocking specifications for the memory bus.
Table 55 provides the clocking specifications for the local bus.

Notes:
1. Caution: The MPX clock to SYSCLK ratio and e600 core to MPX clock ratio settings must be chosen such that the resulting
SYSCLK frequency, e600 (core) frequency, and MPX clock frequency do not exceed their respective maximum or minimum
operating frequencies. Refer to Section 3.1.2, “Platform/MPX to SYSCLK PLL Ratio” and Section 3.1.3, “e600 Core to
MPX/Platform Clock PLL Ratio,” for ratio settings.
2. The minimum e600 core frequency is based on the minimum platform clock frequency of 333 MHz.
3. The reset config pin cfg_core_speed must be pulled low if the core frequency is 800 MHz or below.

1. Caution: The MPX clock to SYSCLK ratio and e600 core to MPX clock ratio settings must be chosen such that the resulting
SYSCLK frequency, e600 (core) frequency, and MPX clock frequency do not exceed their respective maximum or minimum
operating frequencies. Refer to Section 3.1.2, “Platform/MPX to SYSCLK PLL Ratio.”
2. The memory bus clock speed is half the DDR/DDR2 data rate, hence, half the MPX clock frequency.

Note:
1. The local bus clock speed on LCLK[0:2] is determined by the MPX clock divided by the local bus ratio programmed in
LCRR[CLKDIV]. Refer to the
MPC8610 Integrated Host Processor Reference Manual, for more information.
