2.1.2 Differences from H8/300 CPU

In comparison to the H8/300 CPU, the H8/300H has the following enhancements.

• More general registers

Eight 16-bit registers have been added.

• Expanded address space

— Advanced mode supports a maximum 16-Mbyte address space.

— Normal mode supports the same 64-kbyte address space as the H8/300 CPU.

(Cannot be used with the H8/3004 or H8/3005.)

• Enhanced addressing

The addressing modes have been enhanced to make effective use of the 16-Mbyte address

space.

• Enhanced instructions

— Data transfer, arithmetic, and logic instructions can operate on 32-bit data.

— Signed multiply/divide instructions and other instructions have been added.
