1. When using the H8S series E6000 emulator (HS2000EPI61H), 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 ports and checking the bus
states with the MEMORY_FILL command of the pins. 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 Emulator Supplementary Information (HS2214EPI61HE).
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
Select external clock t or t2 with 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), or
input the external clock from the EXTAL terminal on the cable head.
The user system interface cable has the oscillator circuits shown in figure 9.
