The Renesas H8/38076R Group Hardware Manual provides detailed information on the 16‑bit single‑chip microcomputer family, including CPU architecture, system‑control modules and on‑chip peripherals. It is intended for designers who need to understand the hardware functions, pin configurations, register maps and electrical characteristics when integrating the device into their applications.
The manual also includes safety precautions, handling guidelines, and notes on using development tools such as the E7 on‑chip emulator. Revision 3.00 (Mar 18 2005) adds updated specifications and a list of registers for reference.
