IMPORTANT
Note on Memory Expansion or Microprocessor Mode:
z To use memory expansion or microprocessor mode, be sure to set pins RDY#, HOLD# and NMI# so that they
are not held low at startup. Otherwise the emulator system will not start up correctly.
Note on the Target Status POWER LED:
z If your MCU has two or more Vcc terminals, the LED does not light unless power is supplied to all the
terminals.
Note on the Target Status CLOCK LED:
z If the LED is not turned on, check the following.
(1) After powering on the PC7501 (before starting up the emulator debugger):
Make sure that the oscillator circuit board is properly installed in the PC7501 and it is oscillating normally.
(2) After the emulator debugger is started up (after the Init dialog box settings are completed):
Make sure that the oscillator selected in the Init dialog box is oscillating normally.
