Clock Module
7.1
The clock module allows the MCF5271 to be configured for one of several clocking methods.
Clocking modes include internal frequency modulated phase-locked loop (PLL) clocking with
either an external clock reference or an external crystal reference supported by an internal crystal
amplifier. The PLL can also be disabled and an external oscillator can be used to clock the device
directly. The clock module contains:
Freescale Semiconductor
• Crystal amplifier and oscillator (OSC)
• Frequency Modulated Phase-locked loop (PLL)
• Reduced frequency divider (RFD)
• Status and control registers
• Control logic
