Clocking
18.2
MPX to SYSCLK PLL Ratio
The MPX clock is the clock that drives the MPX bus, and is also called the platform clock. The frequency
of the MPX is set using the following reset signals, as shown in Table 68:

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
for ratio settings.
2. The memory bus clock speed is half the DDR/DDR2 data rate, hence, half the MPX clock frequency.

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
for ratio settings.
2. Platform/MPX frequencies between 400 and 500 MHz are not supported.

Notes:
1. The Local bus clock speed on LCLK[0:2] is determined by MPX clock divided by the Local Bus PLL ratio programmed in
LCRR[CLKDIV]. See the reference manual for the MPC8641D for more information on this.
