Note on the Target Status POWER LED: 
 

 

If the MCU has two or more Vcc terminals, the LED does not light unless power is supplied to all the 
terminals. 

 

Notes on the Target Status CLOCK LED: 
 

 

CLOCK LED is turned off when both main and sub clocks are not oscillating. If either clock is oscillating, the 
LED is turned on. 

 

If the LED is not turned on, check the following. 

(1) After powering on the PC4701 (before starting up the emulator debugger): 
 

Make sure that the oscillator circuit board is properly installed in the PC4701 and it is oscillating normally.

(2) After the emulator debugger is started up (after the Init dialog box settings are complete): 
 

Make sure that the oscillator selected in the Init dialog box is oscillating normally.
