1.4 Memory Mapping
Cannot map both emulator memory and user memory in the address area block below at the same time. If
mapped, the previous mapped area changes to guarded area.

1.5 Voltage Follower Circuit
When setting the Vccdown detection voltage in the voltage follower circuit, make the setting be at least 3V
on higher.
1.6 Reserved Area to be Changed for External Address Area
The reserved area that can be changed for the external address area by clearing the RAME bit in the system
control register (SYSCR) to 0 is used as the external address area, change the attribute of this area from
'User Guarded' to 'User Read-write' or 'User Read-only' in the [Memory Mapping] dialog box that is
displayed by selecting [Configure Map...] from the [Memory] menu, before loading the user program.
However, if other attributes than 'User Guarded' are set, an accessing-error break for this area will not occur.
Be careful when the reserved area (RAME = 1) is also used as the external address area (RAME = 0).
1.7 Temporary Breakpoint
·
Run... (Run menu)
Do not set temporary breakpoints to an area wherein PC Break (User Read-only) cannot be set. If set, user
program execution will not stop at the breakpoint. Moreover, the On Chip Breakpoint may remain. In this
case, delete the breakpoint from the [Breakpoints] window.
1.8 Bus Monitor
The bus monitor function cannot be used in power-down modes.
1.9 Monitor
·
Execution status display on status bar
At memory access wait, not the address where access is halted, but the next fetched address is displayed.
1.10 The Load/Save of the Session File
Load the file after you confirm that the H/W environment is the same as that when the last session file was
loaded.
Note that the operation of HDI may become incorrect when Target Clock is chosen at the time when the
session file was saved and Target was not connected at the time when the session file was loaded.
1.11 Load Memory
During loading memory, if loading is stopped by [Halt] from the [Run] menu, there may be no responses
from the HDI for a few seconds. For loading file, use [Load Program] from the [File] menu.
1.12 [Disassembly] Window
At address specification to open the [Disassembly] window, when a value larger than the maximum one of
the absolute address is input, the contents of the last address may not be displayed. In this case, do not
perform scrolling with the scroll box on the scroll bar in the [Disassembly] window.
If nothing is displayed on the Code or Assembly column in the [Memory] window or [Disassembly] window,
close and open again the [Memory] window or [Disassembly] window.
