2.1
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 (architecturally 4-Gbyte) linear address space, and is
ideal for realtime control.
