• Manufacturer: RENESAS [Renesas Technology Corp]

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.
2.1.1
The H8S/2000 CPU has the following features.
• Upward-compatible with H8/300 and H8/300H CPUs
• General-register architecture
• Sixty-five basic instructions
• Eight addressing modes
• 16-Mbyte address space
⎯ Can execute H8/300 and H8/300H object programs
⎯ Sixteen 16-bit general registers (also usable as sixteen 8-bit registers or eight 32-bit
⎯ 8/16/32-bit arithmetic and logic instructions
⎯ Multiply and divide instructions
⎯ Powerful bit-manipulation instructions
⎯ Register direct [Rn]
⎯ Register indirect [@ERn]
⎯ Register indirect with displacement [@(d:16,ERn) or @(d:32,ERn)]
⎯ Register indirect with post-increment or pre-decrement [@ERn+ or @–ERn]
⎯ Absolute address [@aa:8, @aa:16, @aa:24, or @aa:32]
⎯ Immediate [#xx:8, #xx:16, or #xx:32]
