(2) CALLT instruction table area
The 64-byte area 00080H to 000BFH can store the subroutine entry address of a 2-byte call instruction (CALLT). Set the
subroutine entry address to a value in a range of 00000H to 0FFFFH (because an address code is of 2 bytes).
(3) Option byte area
A 4-byte area of 000C0H to 000C3H can be used as an option byte area. For details, see CHAPTER 18 OPTION BYTE.
(4) On-chip debug security ID setting area
A 10-byte area of 000C4H to 000CDH can be used as an on-chip debug security ID setting area. For details, see
CHAPTER 20 ON-CHIP DEBUG FUNCTION.
