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.
the MCU clock: an emulator internal clock and an external clock on the user system. For details,
refer to the Emulator Supplementary Information (HS2633EPI61HE).
To use the emulator internal clock
Select the clock in the emulator station as the system clock ( ), by using the CLOCK
command (emulator command).
To use the external clock on the user system
Select external clock t or t2 with the CLOCK command (emulator command). 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 ( ), or
input the external clock from the EXTAL terminal on the cable head.
Connect a crystal oscillator to the OSC1 and OSC2 terminals for the subclock, or input the
external clock from the OSC1 terminal on the cable head.
refer to section 23, Clock Pulse Generator, in the H8S/2633 Group Hardware Manual.
The user system interface cable has the oscillator circuits shown in figure 10. For details,
