2.3 Frequency Ratio Settings for Processors
The following table shows the available frequency ratios and their
corresponding DIP switch setting. There are 4 switches on SW1. The
black rectangle in the diagram denotes the part that is protruding,
the adjustable switch. Make sure SW1 is set correctly before
applying power, otherwise you will not be able to power-on the
system.
In the example above:
Switch 1: Off
Switch 2: On
Switch 3: Off
Switch 4: On
