Section 4 Verifying Operation

1. When using the E6000 emulator for the H8S/2345 series, turn on the emulator according to the

procedures described in the H8S Series E6000 Emulator User's Manual (HS2000EPI61HE).

2. Verify the user system interface cable connections by accessing the external memory and ports

to check the bus states of the pins 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 cable supports two kinds of clock sources

as the MCU clock: an emulator internal clock and an external clock on the user system. For
details, refer to the H8S/2655 series E6000 Emulator User's Manual (HS2655EPI61HE).
 To use the emulator internal clock

Select the clock in the emulator station as the system clock (

φ), by using 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. Connect a crystal oscillator
to the EXTAL and XTAL terminals for the system clock (

φ). Select the external clock as the

system clock (

φ), by using the CLOCK command (emulator command). For details, refer to

section 18, Clock Pulse Generator in the H8S/2345 Series Hardware.
