3.1.3 Special function register (SFR) area
Table 3-6 Special Function Register List in 3.2.3 Special function registers (SFRs)).
78K0/Kx2-L microcontrollers incorporate the following RAMs.
On-chip peripheral hardware special function registers (SFRs) are allocated in the area FF00H to FFFFH (refer to
Caution Do not access addresses to which SFRs are not assigned.
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, refer to CHAPTER 24 OPTION BYTE.
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, refer to CHAPTER 26 ON-CHIP
DEBUG FUNCTION.
The area 0800H to 0FFFH can perform a direct subroutine call with a 2-byte call instruction (CALLF).
The 32-byte area FEE0H to FEFFH is assigned to four general-purpose register banks consisting of eight 8-bit
registers per bank.
This area cannot be used as a program area in which instructions are written and executed.
The internal high-speed RAM can also be used as a stack memory.
