1. Turn on the emulator according to the procedures described in the SH-2A, SH-2 E200F
Emulator User's Manual (R0E0200F1EMU00E or R0E570800EMU00E).
2. The emulator connected to this user system interface board supports three kinds of clock
sources as the MCU clock. For details, refer to the SH7080 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 70) on the user system interface board or connecting the crystal oscillator to the
XTAL (pin 69) and EXTAL pins. For details, refer to section 4, Clock Pulse Generator, in
the SH7146 Group Hardware Manual.
Figure 12 shows the clock oscillator on the user system interface board.
