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.
as the MCU clock: an emulator internal clock and an external clock on the user system. For
details, refer to the H8S/2633 E6000 Emulator User's Manual (HS2633REPI61HE).
 To use the emulator internal clock
 To use the external clock on the user system
Select the clock in the emulator station with the [CLOCK] option in the [Configuration
Properties] dialog box.
Select external clock (target or target/2) with the [CLOCK] option in the [Configuration
Properties] dialog box, and supply the external clock from the user system to the emulator.
Supply the external clock to the system clock by inputting the external clock from the
EXTAL terminal on the cable head or connecting a crystal oscillator to the EXTAL and
XTAL terminals. To supply the external clock to the subclock, connect the 32.768-kHz
crystal oscillator to the OSC1 and OSC2 terminals. The user system interface cable has the
oscillator circuits shown in figure 10. For details, refer to section 22, Clock Pulse Generator,
in the H8S/2238R Series, H8S/2237 Series Hardware Manual.
