Section 2 CPU
2.1 Overview
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 (4-Gbyte architecturally) linear address space, and is
ideal for realtime control.
2.1.1 Features
The H8S/2000 CPU has the following features.
⢠Upward-compatible with H8/300 and H8/300H CPUs
⯠Can execute H8/300 and H8/300H object programs
⢠General-register architecture
⯠Sixteen 16-bit general registers (also usable as sixteen 8-bit registers or eight 32-bit
registers)
⢠Sixty-five basic instructions
⯠8/16/32-bit arithmetic and logic instructions
⯠Multiply and divide instructions
⯠Powerful bit-manipulation instructions
⢠Eight addressing modes
⯠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 @âERn]
⯠Absolute address [@aa:8, @aa:16, @aa:24, or @aa:32]
⯠Immediate [#xx:8, #xx:16, or #xx:32]
⯠Program-counter relative [@(d:8,PC) or @(d:16,PC)]
⯠Memory indirect [@@aa:8]
⢠16-Mbyte address space
⯠Program: 16 Mbytes
⯠Data: 16 Mbytes (4 Gbytes architecturally)
