1. Turn on the emulator according to the procedures described in the H8S Family E6000 Emulator
2. Verify the user system interface cable connections by accessing the external memory and ports to
3. The emulator connected to this user system interface cable supports two kinds of clock sources as

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.
the MCU clock: an emulator internal clock and an external clock on the user system. For details,
refer to the H8S/2628 Group E6000 Emulator Supplementary Information (HS2628EPI61HE).
Figure 9 shows the oscillator circuit on the user system interface cable.
To use the emulator internal clock
Select the clock in the emulator station as the system clock ( ), by using the CLOCK
command (emulator command).
To use the external clock on the user system
Select external clock Target or Target/2 with the CLOCK command (emulator command).
Supply the external clock from the user system to the emulator by inputting the external clock
from the EXTAL terminal on the cable head or connecting a crystal oscillator to the EXTAL
and XTAL terminals. For details, refer to the Clock Pulse Generator section, in the H8S/2628
Group Hardware Manual.
