Section 4 Verifying Operation
1. When using the H8/3052 series E6000 emulator (HS3052EPI61H), turn on the emulator
according to the procedures described in the H8/300H Series E6000 Emulator User's Manual
(HS300HEPI61HE).
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 H8/3052 Series E6000 Emulator User's Manual (HS3052EPI61HE).
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 the target clock (t or t2) as the system clock (φ), by using 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 section 13,
Clock Pulse Generator, in the H8/3001 Hardware Manual.
Figure 9 shows the oscillator circuit on the user system interface cable.
