• Manufacturer Part Number: HD6413008F
• Description: Renesas 16-Bit Single-Chip Microcomputer H8 Family/H8/300H Series
• Manufacturer: RENESAS [Renesas Technology Corp]

2.1
The H8/300H CPU is a high-speed central processing unit with an internal 32-bit architecture that
is upward-compatible with the H8/300 CPU. The H8/300H CPU has sixteen 16-bit general
registers, can address a 16-Mbyte linear address space, and is ideal for realtime control.
2.1.1
The H8/300H CPU has the following features.
• Upward compatibility with H8/300 CPU
• General-register architecture
• 64 basic instructions
• Eight addressing modes
• 16-Mbyte linear address space
• High-speed operation
Can execute H8/300 Series object programs
Sixteen 16-bit general registers (also usable as sixteen 8-bit registers or eight 32-bit registers)
⎯ 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:24, ERn)]
⎯ Register indirect with post-increment or pre-decrement [@ERn+ or @–ERn]
⎯ Absolute address [@aa:8, @aa:16, or @aa:24]
⎯ Immediate [#xx:8, #xx:16, or #xx:32]
⎯ Program-counter relative [@(d:8, PC) or @(d:16, PC)]
⎯ Memory indirect [@@aa:8]
⎯ All frequently-used instructions execute in two to four states
⎯ Maximum clock frequency:
