Notes on Memory Access:
• When setting processor mode to the memory expansion mode, it may be changed to
the memory expansion mode temporarily before the user program itself changes
from the single-chip mode to the memory expansion mode. Take due consideration
on this phenomenon in the following cases:
(1) Immediately before executing the program after setting a software break
(2) Immediately after stopping the program when a software break is set
• To refer to or change the contents of emulation memory for expansion, its processor
mode should be either memory expansion mode or microprocessor mode. In
memory expansion mode, after the emulator debugger starts or it is reset, processor
mode shifts to single-chip mode automatically, therefore, you need to change
processor mode bit using a memory window or others.
(5) Referring MCU STATUS
It is possible to confirm each level of pins BYTE, CNVss, RDY*, HOLD* and NMI* on the target
system.
Notes on MCU STATUS:
• The status of pins of MCU is displayed in the "MCU STATUS" of the EMEM dialog
box. Confirm if it matches with processor mode.
• Check that "RDY", "HOLD" and "NMI" are set to "H". If they are set to the "L" level,
the MCU itself is in the standby state. The emulator debugger displays an error
message because it receives no response from the MCU.
