5. Debugging Functions
(3) Methods of setting protection
There are the following two methods:
- Automatic setting by section information in a downloaded module
- Individually specifying an access attribute for an area
(4) Method of detection
Violation of access protection is detected by internal resources (blocks 1–16) of the emulator.
The blocks are automatically allocated by an original algorithm of the emulator.
CAUTION
Since the emulator’s internal resources are limited, not all blocks can be protected. If an error occurs, reduce the number of
assigned blocks by using the ‘Delete’ button before setting protection again.
