Section 4   Verifying Operation 

1.  Turn on the emulator according to the procedures described in the H8SX/1650 E6000H Emulator 

User's Manual (HS1650EPH60HE). 

2.  Verify the user system interface cable connections by checking the pin states with the CHECK 

command (emulator command).  If an error is detected, recheck the soldered IC socket and the 
location of pin 1. 

3.  The emulator connected to this user system interface cable supports three kinds of clock sources 

as the MCU clock: an emulator internal clock, an external clock on the user system, and a crystal 
oscillator to be mounted on the EV-chip board.  For details, refer to the H8SX/1650 E6000H 
Emulator User's Manual (HS1650EPH60HE). 



  To use the emulator internal clock 

Select the clock in the emulator by using the CLOCK command (emulator command). 



  To use the external clock on the user system 

Select the external clock with the CLOCK command (emulator command).  Supply the 
external clock from the user system to the emulator by inputting the external clock from the 
EXTAL terminal on the cable head or connecting a crystal oscillator to the EXTAL and 
XTAL terminals.  For details, refer to the H8SX/1520 Group Hardware Manual. 



  To use the crystal oscillator mounted on the EV-chip board 

Install a crystal oscillator into the crystal oscillator terminals on the EV-chip board. 

Figure 9 shows the oscillator circuit on the user system interface cable.
