Two CPU operating modes
Low-power mode
Transition to power-down state by SLEEP instruction
More general registers
Eight 16-bit registers have been added.
Expanded address space
Enhanced addressing
The addressing modes have been enhanced to make effective use of the 16-Mbyte address
space.

Normal mode
Advanced mode
Advanced mode supports a maximum 16-Mbyte address space.
Normal mode supports the same 64-kbyte address space as the H8/300 CPU.
Data transfer, arithmetic, and logic instructions can operate on 32-bit data.
Signed multiply/divide instructions and other instructions have been added.
