Section 5 Verifying Operation
1. Turn on the emulator according to the procedures described in the SH7211 E200F Emulator
User's Manual (R0E0200F1EMU00E or R0E572110VKK00E).
2. Verify the user system interface cable connections by checking the pin states with the
extended monitor and checking the bus states with the 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 board supports three kinds of clock
sources as the MPU clock. For details, refer to the SH7211 E200F Emulator User's Manual
(R0E0200F1EMU00E).
⎯ To use the emulator internal clock
Select the clock in the emulator by the CLOCK command (emulator command).
⎯ To use the external clock on the user system
Supply the external clock from the user system to the emulator by inputting the EXTAL
pin (pin 26) on the user system interface board or connecting the crystal oscillator to the
XTAL (pin 25) and EXTAL pins. For details, refer to the section of Clock Pulse Generator
in the SH7211 Group Hardware Manual.
Figure 10 shows the clock oscillator on the user system interface board.
