The H8S/2600 Series and the H8S/2000 Series are built around an H8S/2000 CPU core.
The H8S/2600 and H8S/2000 CPUs have the same internal 32-bit architecture. Both CPUs
execute basic instructions in one state, have sixteen 16-bit registers, and have a concise, optimized
instruction set. They can address a 16-Mbyte linear address space.Programs coded in the high-
level language C can be compiled to high-speed executable code.
For easy migration, the instruction set is upward-compatible with the H8/300H, H8/300, and
H8/300L Series at the object-code level.
The H8S/2600 CPU is upward-compatible with the H8S/2000 CPU at the object-code level, and
supports sum of products instructions.
This manual gives details of the H8S/2600 and H8S/2000 instructions and can be sued with all
microcontrollers in the H8S/2600 Series and the H8S/2000 Series.
For hardware details, refer to the relevant microcontroller hardware manuals.
