On-Chip Clock Synthesis (OCCS)
15.1
15.1.1 Overview
This module provides the 2X system clock frequency to the system integration module
(SIM), which then generates the various derivative system and peripheral clocks for the
chip.
The on-chip clock synthesis module allows product design using several user selectable
clock sources including an internal relaxation oscillator and PLL to run at frequencies up
to a 60MHz system clock.
15.1.2 Features
The on-chip clock synthesis (OCCS) module interfaces to the oscillator and PLL. The
device has more options for clock generation than do the other members of the
MC56F8000 family. The OCCS clock sources include:
Additional OCCS module features are as follows:
Freescale Semiconductor
• On-Chip Relaxation Oscillator (ROSC). This module nominally generates an 8MHz
• Crystal Oscillator (COSC). This module is designed for use with a crystal or

clock signal. It is also capable of operating at 400KHz when the device is in low
power mode.
resonator in the 4 to 16MHz range. When used with the on-chip PLL of this device,
the maximum crystal/resonator frequency is 16MHz.
