Section 3 Verifying Operation
1. Turn on the emulator according to the procedures described in the H8SX/1650 Series 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) and checking the bus states with the FILL 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 board supports three kinds of clock s ources
as the MCU clock. For details, refer to the H8SX/1650 Series E6000H Emulat or Us er's Manual
(HS1650EPH60HE).
To use the emulator internal clock
Select the clock in the emulator by the CLOCK command (emulator command).
To use the external clock on the user system
Supply the external clock from the user system to the emulator by inputting the EXTAL pin
(pin 84) on the user system interface board or connecting the crystal oscillator to the XTAL
(pin 83) and EXTAL pins. For details, refer to the H8SX/1650 Hardware Manual.
Figure 8 shows the clock oscillator on the user system interface board.
