In comparison with the H8/300 CPU, the H8S/2600 CPU and H8S/2000 CPU have the following
More general registers and control registers
Expanded address space
Eight 16-bit registers, one 8-bit and two 32-bit control registers have been added.
Normal mode supports the same 64-kbyte address space as the H8/300 CPU.
Advanced mode supports a maximum 4-Gbyte address space.
The addressing modes have been enhanced to make effective use of the 4-Gbyte address
Addressing modes of bit-manipulation instructions have been enhanced.
Signed multiply and divide instructions have been added.
A multiply-and-accumulate instruction has been added. (H8S/2600CPU only)
Two-bit shift and rotate instructions have been added.
Instructions for saving and restoring multiple registers have been added.
A test and set instruction has been added.
Basic instructions execute twice as fast.
