Clock system
The C868 clock system consist of the on-chip oscillator, PLL and multiplexer stage. The
programmable Slow Down Divider (SDD) divides the PLL output clock frequency by a
factor of 1...32 which is specified via CMCON.REL. The system clock is switched from
the PLL output to the output from the SDD when slowdown mode is selected.
