PURPOSE:To avoid generation of mis-synchronization completely at a receiver side by using a transmitter so as to and a 1-bit data to a serial data in a character of transmission purpose and a synchronization character on a transmission serial data when the serial data and the circuit clock are sent and received. CONSTITUTION:A pattern for character synchronization is made up of <bit of level 1>+<character whose bits are all 1>+<bit of level 0>+<character whose bits are all 0>. Moreover, the bit pattern of a character being an object of transmission at transmission consists of <bit of level 0>+<character of transmission object>, then a pattern for character synchronization does not appear in the bit pattern of the character string being transmission object and mis-synchronization of the character synchronization pattern due to the detection timing in the receiver is absolutely avoided. |
