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
EXMONITOR_DISPLAY command (emulator command) and checking the bus states with
the MEMORY_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
sources as the MCU clock. 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 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 signal to
the EXTAL pin (pin 98) on the user system interface board or connecting a crystal
oscillator to the XTAL (pin 97) and EXTAL pins. For details, refer to the H8SX/1650
Hardware Manual.
Figure 15 shows the clock oscillator on the user system interface board.
