1. When using the H8S/2556, H8S/2552, and H8S/2506 groups E6000 emulator, turn on the

emulator according to the procedures described in the H8S/2556, H8S/2552, and H8S/2506

groups E6000 Emulator User's Manual (HS2556EPI61HE).

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

as the MCU clock: an emulator internal clock and an external clock on the user system. For

details, refer to the H8S/2556, H8S/2552, and H8S/2506 groups E6000 Emulator User's Manual

(HS2556EPI61HE).

 To use the emulator internal clock

Select the clock in the emulator station with the [CLOCK] option in the [Configuration

Properties] dialog box.

 To use the external clock on the user system

Select external clock (target or target/2) with the [CLOCK] option in the [Configuration

Properties] dialog box, and supply the external clock from the user system to the emulator.

Supply the external clock to the system clock by inputting the external clock from the

EXTAL terminal on the cable head or connecting a crystal oscillator to the EXTAL and

XTAL terminals. To supply the external clock to the subclock, connect the 32.768-kHz

crystal oscillator to the OSC1 and OSC2 terminals. For details, refer to section 21, Clock

Pulse Generator, in the H8S/2556, H8S/2552, and H8S/2506 groups Hardware Manual.

The user system interface cable has the oscillator circuits shown in figure 10. This circuit is

located on the lower board of the H8S/2556, H8S/2552, and H8S/2506 groups.
