RECEIVER AND SEMICONDUCTOR DEVICE BASED ON ASYNCHRONOUS COMMUNICATION USING MANCHESTER CODE

摘要

PROBLEM TO BE SOLVED: To provide a communication method which provides an error detecting means of a physical layer and can be used in an environment (system) in which a clock is not stable in an asynchronous communication using Manchester code.;SOLUTION: Decision of received data of the asynchronous communication is performed not only by one bit length unit but also by two bit length unit. A first two bit data count 6-1 and a second two bit data count 6-2 are made to operate after being shifted by time slot one bit, then decision of data is performed alternately. Error detection of data is performed by contrasting data output by a timing signal output by the first 2 bit data count 6-1 and the second 2 bit data count 6-2 with data to be output by a normal one bit length unit.;COPYRIGHT: (C)2011,JPO&INPIT
