Clock Generation Module
In FCS, this module simulates all functionality of the Clock Generation Module (ICG),
including:
• Phase Locked Loop (PLL) generation
• Automatic lock detection
•Interrupt
• Acquisition
• Tracking
• Flag polling
FCS mode uses simulated External Oscillator Frequency change command (XTAL) to
allow the user to input the desired XTAL value. To check the current value of the External
Oscillator, Bus Frequency and CGMXCLK Frequency, open the HCS08FCS menu, then
select Clocks Module > Show MCU Clocks.

Once you select the MCU Clocks Menu, the Cycles Window displays all of the above-
mentioned Clock Frequencies.
