The E1/E20/EZ Emulator disables the area protection when it is to download a user program in the flash ROM area that is protected from programming by the area protection.
The behavior of the emulator depends on the setting of the [Debug the program re-writing the on-chip PROGRAM ROM] property in the [System] [E1] [E20] [EZ Emulator] category on the [Debug Tool Settings] tab of the Property panel.
The area protection is restored after downloading.
The area protection remains disabled even after downloading.
For products of these groups, settings for area protection are restored after downloading has been completed, regardless of the setting of the [Debug the program re-writing the on-chip PROGRAM ROM] property.
