Abstract

There are provided a method and an interface system for Bidirectional Synchronous Serial (BISS) protocol data decoding. The method includes: an MA drive module receiving an enable signal en and transmitting an MA clock signal to an SL receiving module, and then the SL receiving module detecting a trigger signal of SL; when a start bit of the SL is detected by the SL receiving module, the SL receiving module reading SL data; after the SL data is read, the SL receiving module transmitting a done signal to the MA drive module to stop operation of the MA drive module and transmitting a did signal to a CRC check module; and after the did signal is received by the CRC check module, the CRC check module performing CRC check on the SL data and outputting a correct position value after the check is completed.
