Clock MODE S3 (switch 6, 7 and 8)
The CPU-clock can be derived either directly from the oscillator
clock or from the on-chip PLL that allows definition of a prescaler.
To determine the clock source and the prescaler port P0.13 -P0.15
must be configured with DIP-Switch S3 (switch 6, 7 and 8) during
system reset. The standard version of the kitCON-161CS/JC/JI is
equipped with a 5 MHz quartz (XT1) meaning that the frequency of
the CPU clock is 20 MHz with the default jumper setting.
