Section 4 Verifying Operation

1.When using the E6000 emulator for the H8S/2633 group, turn on the emulator according to the procedures described in the H8S Family 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 external clock t or t2 with the CLOCK command (emulator command). Supply the external clock from the user system to the emulator.

Connect a crystal oscillator to the EXTAL and XTAL terminals for the system clock (φ ), or input the external clock from the EXTAL terminal on the cable head.

Connect a crystal oscillator to the OSC1 and OSC2 terminals for the subclock, or input the external clock from the OSC1 terminal on the cable head.

The user system interface cable has the oscillator circuits shown in figure 10. For details, refer to section 23, Clock Pulse Generator, in the H8S/2633 Group Hardware Manual.
