Hardware Setup
CPU Oscillator
Jumper JP2 selects the oscillator that will be used by the
microprocessor. The setting is based on the speed of the microproces­
sor. The jumper is factory set for the 32 Mhz oscillator, the setting for
the 16 Mhz microprocessor. This default setting will not need adjust­
ment. In a 20MHz CPU model the board will operate at 20MHz by
adding an oscillator. Short pins 1-2 (default) for 32 Mhz, OSC1; pins
2-3 for option oscillator, OSC2. The factory setting (short 1-2) is
shown in the figure below.
