Abstract

Bit stuffing is used in asynchronous serial pro- atier each n (e.g., 5) bits of the same value in the tocols with relatively long messages (e.g., CAN pro- transmitter, while the receiver uses the transition tocol) and thus a need exists to supply the receiver and then deletes the artificially-inserted bit. The use enough transitions for synchronization. The imple- of bit-stuffing decreases the throughput of the serial mentation is to add an artificial, opposite-value bit line, and also adds logic for bit insertion/deletion.
