3. CPU external frequency selection (DSW1 Switches 1-6)
This option tells the clock generator what frequency to send the CPU.
This allows the selection of the CPU’s external frequency (or Bus
Clock). The BUS Clock multiplied by the Frequency Multiple equals the
CPU’s internal frequency (the advertised CPU speed).
Set the CPU frequency only to the recommended settings.
Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable.
To select the CPU external frequency using the DIP switches, ensure
that the JEN jumper is set to jumper mode.
