Section 4   Verifying Operation 
1.  When using the E6000 emulator for the H8S/2655 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 Supplementory Information (HS2655EPI61HE). 
  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 
Supply the external clock from the user system to the emulator.  Connect a crystal 
oscillators to the EXTAL and XTAL terminals for the system clock.  Select the external 
clock as the system clock (
φ
), by using the CLOCK command (emulator command).  The 
user system interface cable has the oscillator circuits shown in figure 10.  For details, refer 
to section 20, Clock Pulse Generator, in the H8S/2655 Group Hardware Manual.
