Renesas H8S/2237 Series Manual De Usuario

Section 4   Verifying Operation 

1.  When using the E6000 emulator for the H8S/2633 series, turn on the emulator according to the 

procedures described in the H8S Series 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 H8S/2633 series E6000 Emulator User's Manual (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 

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).  Select the external clock as the 

system clock (

φ), by using the CLOCK command (emulator command).  For details, refer to 

section 19, Clock Pulse Generator in the H8S/2237 Series Hardware Manual and section 20, 
Clock Pulse Generator, in the H8S/2238 Series Hardware Manual.
