Section 4 Verifying Operation
1. When using the E6000 emulator for the H8S/2636 and H8S/2646 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/2636 and H8S/2646 series E6000 Emulator User's Manual
(HS2646EPI61HE).

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. Input the external clock
pulse from the cable head EXTAL terminal, or 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 the section
on Clock Pulse Generator in the H8S/2282 Series Hardware Manual.
