Vector Table Address
Vector table area
The 34-byte area of addresses 0000H to 0021H is reserved as a vector table area. This area stores program
start addresses to be used when branching by RESET input or interrupt request generation.
16-bit address, the lower 8 bits are stored in an even address, and the higher 8 bits are stored in an odd
address.
CALLT instruction table area
The subroutine entry address of a 1-byte call instruction (CALLT) can be stored in the 64-byte area of
addresses 0040H to 007FH.
Option byte area
The option byte area is the 1-byte area of address 0080H. For details, refer to CHAPTER 18 OPTION
BYTE.
Protect byte area
The protect byte area is the 1-byte area of address 0081H. For details, refer to CHAPTER 19 FLASH
MEMORY.
