The H8S/2000 CPU is a high-speed central processing unit with an internal 32-bit architecture that
is upward-compatible with the H8/300 and H8/300H CPUs. The H8S/2000 CPU has sixteen 16-bit
general registers, can address a 16-Mbyte linear address space, and is ideal for realtime control.
This section describes the H8S/2000 CPU. The usable modes and address spaces differ depending
on the product. For details on each product, refer to section 3, MCU Operating Modes.
