Low speed serial bus protocol and circuitry |
摘要 |
A serial bus communications method and circuitry for low speed serial bus functions. Over a two-wire communications channel, a unidirectional clock line and a bidirectional data line are used to transfer data. A protocol defines permissions, acknowledgments, terminations and retries handshaking between points. Circuitry is provided for reducing the latency of the serial bus when cooperating with the low speed functions. A resistive connection scheme is disclosed for converting high voltage signals into lower voltage signals.
