1. When using the E6000 emulator for the H8S/2633 series, 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 the external memory and ports

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.

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 (HS2633EPI61HE).

 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 the target clock Target or Target/2 with 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, and the subclock from OSC1 and OSC2. For details, refer to

the Clock Pulse Generator section, in the H8S/2643 Series Hardware Manual.

Figure 10 shows the oscillator circuit on the user system interface cable.
