Section 4 Verifying Operation
1. When using the H8/300 series E6000 emulator (HS3008EPI60H), turn on the emulator
according to the procedures described in the H8/300 Series E6000 Emulator User's Manual
(HS3008EPI60HE).
2. Verify the user system interface cable connections by accessing the external memory and ports
to check the bus states 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: an emulator internal clock and an external clock on the user system. For details, refer
to the H8/300 Series E6000 Emulator User's Manual (HS3008EPI60HE).
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 as the system clock
Select target 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. In the H8/3297 series, the system
clock (φ) has the same frequency as the external clock, and in the H8/329 series, the system
clock has a half frequency of the external clock.
Figure 9 shows the oscillator circuit on the user system interface cable.
