The 64-byte area 0040H to 007FH can store the subroutine entry address of a 1-byte call instruction (CALLT).
A 5-byte area of 0080H to 0084H and 1080H to 1084H can be used as an option byte area. Set the option byte
at 0080H to 0084H when the boot swap is not used, and at 0080H to 0084H and 1080H to 1084H when the boot
swap is used. For details, see CHAPTER 18 OPTION BYTE.
The area 0800H to 0FFFH can perform a direct subroutine call with a 2-byte call instruction (CALLF).
A 10-byte area of 0085H to 008EH and 1085H to 108EH can be used as an on-chip debug security ID setting
area. Set the on-chip debug security ID of 10 bytes at 0085H to 008EH when the boot swap is not used and at
0085H to 008EH and 1085H to 108EH when the boot swap is used. For details, see CHAPTER 20 ON-CHIP
DEBUG FUNCTION.
