Multi-Purpose Clock Generator (S08MCGV2)
8.1
The multi-purpose clock generator (MCG) module provides several clock source choices for the MCU.
The module contains a frequency-locked loop (FLL) and a phase-locked loop (PLL) that are controllable
by either an internal or an external reference clock. The module can select either of the FLL or PLL clocks,
or either of the internal or external reference clocks as a source for the MCU system clock. Whichever
clock source is chosen, it is passed through a reduced bus divider which allows a lower output clock
frequency to be derived. The MCG also controls an external oscillator (XOSC) for the use of a crystal or
resonator as the external reference clock.
All devices in the MC9S08DZ128 Series feature the MCG module.
