(3) Methods for setting protection
There are following two methods of specification:
- Automatic setting by section information in a download module
- Specifying the access attribute of any area individually
(4) Detection method
An access protect violation is detected by the emulator’s internal resources (blocks 1–16).
The blocks are automatically allocated by the emulator’s exclusive algorithm.
CAUTION
Since the emulator’s internal resources are limited, not all blocks can be access protected. In that case, reduce the amount of
used blocks by “removing blocks” before setting protection again.

you can display a warning in the Status window and in a status bar balloon.
- Make the detection of an access protect violation a condition of a hardware breakpoint
- Make the detection of an access protect violation a condition of a trace point
