Serial data receiver

摘要

A serial data receiver receives a serial data including first data defined as a judgment data indicative of at least one of a data reception rate and a reception data length. A shift register receives the serial data. The first data of the serial data received by the shift register is decoded by a decoder. The decoded result of the decoder is stored in a state register. A control circuit determines at least one of a data reception rate and a reception data length for the reception of the second and subsequent data of the serial data by the shift register based on the decoded result stored in the state register.
