Section 3 Verifying Operation
1. Turn on the emulator according to the procedures described in the SH7058 E6000H Emulator
User's Manual (HS7058EPH60HE).
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 MCU clock. For details, refer to the SH7058 E6000H Emulator User's Manual
(HS7058EPH60HE).

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 A14) on the user system interface board or connecting the crystal oscillator to the
XTAL (pin A15) and EXTAL pins. For details, refer to section 5, Clock Pulse Generator
(CPG), in the SH7058 Hardware Manual.
Figure 8 shows the clock oscillator on the user system interface board.
