Abstract:
    The invention relates to a variable length coding method and its circuit. It includes address coding. When the address coding length is not more than 20 bits, one moment high level impulse signal can make the counter reset and recount. The method can realize multi-digit address coding without adding trigger. The circuit has simple application circuit structure, can realize 20, 22, 23, 24 bits address coding, reduce chip area, and reduce coding recurrence rate. The method and circuit can be used in wireless coding remote controller chip, various fields that anti-theft device, industry remote control, toy remote control etc.
