3. When boot swap is not used: Set the option bytes to 0080H to 0084H, and the on-chip debug security
When boot swap is used:
During on-chip debugging, about 7 to 16 bytes of this area are used as the user data backup area for
communication.
During on-chip debugging, use of this area is disabled because it is used as the communication
command area (008FH to 018FH: debugger’s default setting).
