■ Guarded Access Breaks
A guarded access break suspends a executing program when accessing in violation of the access attribute
set by using the [Setup]-[Memory Map] command, and accessing a guarded area (access-disabled area in
undefined area).
Guarded access breaks are as follows:
• Code Guarded
An instruction has been executed for an area having no code attribute.
• Read Guarded
A read has been attempted from the area having no read attribute.
•Write Guarded
A write has been attempted to an area having no write attribute.
If a guarded access occurs while executing a program, the following message is displayed on the Status Bar
and the program execution suspended.
