Table 3-1: Default Status of Jumpers/Switches
To operate the unit stand alone on the bench top, connect the +5V power supply to the
Power Socket at the back of the unit.
The front-panel POWER LED should be illuminated indicating that the +3.3V power is active.
Upon power on, the Processor will start executing instructions beginning at the memory
location 0x00000000, which is the start of the PROM. If the PROM is 'empty' or no valid
program is installed, the first executed instruction will be invalid, and the processor will halt
with an ERROR condition, with the ERROR LED illuminated.
Pressing the DSU-BREAK button should illuminate the DSUACT LED and halt the
processor.
