78K0/KC1+ products incorporate the following internal high-speed RAMs.
The 32-byte area FEE0H to FEFFH is assigned to four general-purpose register banks consisting of eight 8-bit
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.
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).
The option byte area is assigned to the 1-byte area of 0080H. Refer to CHAPTER 22 OPTION BYTE for details.
The area 0800H to 0FFFH can perform a direct subroutine call with a 2-byte call instruction (CALLF).
