Renesas H8S/2328 Series, TFP-120 Section 4 Verifying Operation

Section 4 Verifying Operation

1. When using the E6000 emulator for the H8S/2328 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 c ommand (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 (HS2338EPI61HE and

HS2339EPI61HE).

 To use the emulator internal clock

Select the clock in the emulator station as the system clock (φ), by using the CLOCK

command (emulator comman d).

 To use the external clock on the user system

Select external clock t or t2 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. For details, refer to section 22, Clock Pulse Generator, in the H8S/2338

Series, H8S/2328 Series, H8S/2318 Series Hardware Manual.

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