2.4.9 Disabling Memory Access to Specified Area

This section explains the access-prohibited area.

■Access-prohibited Area

The access-prohibited area has a function to inhibit memory access when the debugger tries to access the
memory in the specified area (*1). However, it does not inhibit memory access from the program.
(*1) The following shows the memory access by the commands or window operations.
- Memory operation commands
- Assemble/disassemble commands
- Load/save commands
- Built-in functions (%BIT, %B, %H, %W, %L, %S, %D)
- Formula
- Trace
- Vector
- Memory window
- Source window
- Disassemble window
- Watch window
- Local window
- Symbol window
■How to set
The access-prohibited area can be set by the following command.
• Dialog
- "Access-prohibited area" tab in the debug environment setting dialog
For details, refer to "4.7.2.3 Debug Environment Setting" in "SOFTUNE Workbench Operation
Manual" for details.
• Command
- SET MAP /INACCESSIBLE
For details, refer to "1.14 SET MAP (type2)" in "SOFTUNE Workbench Command Reference
Manual for details".
Note:
If the range to be accessed also includes an access-prohibited area, access is made to memory just
before the access-prohibited area. Once the access-prohibited area is reached, an error is
generated to suspend the memory access.
