<processor> (HD6309) Hitachi's version of the Motorola
6809 microprocessor. Compatible with the 6809, it added
two new eight-bit registers that could be added to form a
second 16-bit register, and all four eight-bit registers could
form a 32-bit register. It also featured division, and some
32-bit arithmetic and was generally 30% faster in native mode.
This information, surprisingly, was never published by
Hitachi.
