CHAPTER 3 CPU ARCHITECTURE
(2) CALLT instruction table area
The 64-byte area 0040H to 007FH can store the subroutine entry address of a 1-byte call instruction (CALLT).
(3) Option byte area
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 23 OPTION BYTE.
(4) CALLF instruction entry area
The area 0800H to 0FFFH can perform a direct subroutine call with a 2-byte call instruction (CALLF).
(5) On-chip debug security ID setting area
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 25 ON-CHIP
DEBUG FUNCTION.
