Figure 4. MPC750 Microprocessor Signal Groups
1.1.9 Clocking
The MPC750 requires a single system clock input, SYSCLK, that represents the bus interface frequency.
Internally, the processor uses a phase-locked loop (PLL) circuit to generate a master core clock that is
frequency-multiplied and phase-locked to the SYSCLK input. This core frequency is used to operate the
internal circuitry.
