IMPORTANT
Note on Microprocessor Mode:
• To use or microprocessor mode, be sure to set pins RDY* and HOLD* so that they
are not active at startup. Otherwise the emulator system will not function correctly.
Note on CLOCK LED:
• If CLOCK LED does not turn on, check the following:
(1) Immediately after starting PC4701 (before starting the emulator debugger)
--> Check if the oscillation circuit within the emulation pod oscillates normally.
(2) After starting up the emulator debugger (after setting the Init dialog box)
--> Check the oscillation circuit set in the Init dialog box oscillates normally.
• If this LED does not light, check the voltage
of the target system.
• Check that power is supplied to all the
power terminals.
• When the target system is not connected,
this LED does not light.
• When this LED lights, check the reset pin of
the target system.
