1. When using the E6000 emulator (HS2148EPI61H) for the H8S/2148, H8S/2138, H8S/2128
2. Verify the user system interface cable connections by accessing the external memory and ports
3. The emulator connected to this user system interface cable supports two kinds of clock sources

series, turn on the emulator according to the procedures described in the H8S Series E6000
Emulator User's Manual (HS2000EPI61HE).
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.
as the MCU clock: an emulator internal clock and an external clock on the user system. For
details, refer to the H8S series E6000 Emulator User's Manual (HS2000EPI61HE).
 To use the emulator internal clock
 To use the external clock on the user system
Figure 9 shows the oscillator circuit on the user system interface cable.
Select the clock in the emulator station as the system clock (φ), by using the CLOCK
command (emulator command).
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 22, Clock Pulse Generator, in the H8S/2138 Series, H8S/2134 Series Hardware
Manual.
