Section 5 Verifying Operation
1. When using the H8S/2214 E6000 emulator for the H8S/2218 series, turn on the emulator
according to the procedures described in the H8S/2214 E6000 Emulator User's Manual
(HS2214EPI62HE).
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/2214 E6000 Emulator User’s Manual (HS2214EPI62HE).
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 19, Clock
Pulse Generator, in the H8S/2218 Series Hardware Manual.
The user system interface cable has the oscillator circuits shown in figure 11. This circuit is
located on the lower board of the HS2218ECN61H.
