CPU clock speed selection
Eight 16-bit expanded registers, and 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 16-Mbyte address space.
The addressing modes have been enhanced to make effective use of the 16-Mbyte address
space.
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.
Two-bit shift instructions have been added.
Instructions for saving and restoring multiple registers have been added.
A test and set instruction has been added.
