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/1648

Group Hardware Manual.

Figure 17 shows the clock oscillator on the user system interface board.
