⎯ 32 ÷ 16-bit register-register divide:
⎯ Normal mode
⎯ Advanced mode
Transition to power-down state by SLEEP instruction
Eight 16-bit registers have been added.
⎯ Advanced mode supports a maximum 16-Mbyte address space.
⎯ Normal mode supports the same 64-kbyte address space as the H8/300 CPU.
The addressing modes have been enhanced to make effective use of the 16-Mbyte address
space.
⎯ Data transfer, arithmetic, and logic instructions can operate on 32-bit data.
⎯ Signed multiply/divide instructions and other instructions have been added.
