Abstract
A system and process are disclosed for automatically resuming data communication using an IEEE-1394 PHY when communication is suspended because input bias is momentarily lost. The PHY determines whether data communication is suspended due to the PHY being disconnected from a network by checking the status of a connected flag. If the connected flag is still set to TRUE, the PHY was not intentionally disconnected from the network and it automatically attempts to resume communication by setting a resume flag to TRUE. The invention finds application in any type of communication device using the IEEE-1394 high-speed serial bus standard including audio and video sources, which may readily be connected to a personal computer for data storage or editing. The system and process may be implemented using software code and included within a digital signal processor (DSP).
