H8/300H Tiny

The H8/300H Series is built around a 32-bit H8/300H CPU core with sixteen 16-bit registers, a concise, optimized instruction set designed for high-speed operation, and a 16-Mbyte linear address space. For easy migration from the H8/300 Series, the instruction set is upwards-compatible with the H8/300 Series at the object-code level. Programs coded in the high-level language C can be compiled to high-speed executable code. This manual gives details of the H8/300H CPU instructions and can be used with all microcontrollers in the H8/300H Series. For hardware details, refer to the relevant microcontroller hardware manual.
