ASYNCHRONOUS SERIAL INFORMATION RECEIVER AND ASYNCHRONOUS SERIAL INFORMATION TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To obtain an asynchronous serial information receiver and an asynchronous serial information transmitter on the basis of asynchronous serial information transmission reception system by setting a baud rate in the asynchronous serial information receiver being a reception section and the asynchronous serial information transmitter being a transmission section in the asynchronous serial information transmission reception in more details so as to enhance a maximum value of the baud rate without revising an operating clock frequency of the reception section and the transmission section.;SOLUTION: In the asynchronous serial transfer in the asynchronous serial information receiver, A control signal generating circuit 1 receives a count correction signal 15 from a count correction circuit 2, generates and outputs a data shift signal 120. A serial parallel conversion circuit 3 changes a sampling interval of communication data 4 for each bit on the basis of the data shift signal 120 to set a sampling interval in more details than an integer multiple of an operating clock 110 thereby enhancing a maximum baud rate.;COPYRIGHT: (C)2000,JPO
