Introduction of LC8635XX hardware characteristics and software functions, including color format, audio format, mono or stereo function, subwoofer control function, boot screen function, one to three AV input function, S-VIDEO input function, YUV input function, perpetual calendar function, etc.
This manual describes the LC8635XX CPU used with LA76810 or LA76818 to achieve TV+DVD two‑in‑one control or single TV operation. It outlines the hardware characteristics such as RAM, ROM, I/O ports, PWM outputs, timers, and interrupt sources, as well as the software functions like channel selection, audio modes, and special features.
The document includes detailed pin‑out diagrams, port definitions, key and remote‑control mappings, and configuration procedures for functions such as hotel mode, SCART auto‑detect, and factory logo display. It also covers factory debugging, EEPROM calibration, and automatic debugging enable pins. This manual is written in Chinese.
