Data communication characteristic detection in communication device, involves supplying clock signal generated to receive serial data, to UART for setting detected data communication characteristics

摘要

The method involves judging whether the received serial data contains At instruction, based on which data communication characteristic including band rate, parity type and data format of received serial data, is detected. A clock signal for receiving the serial data is generated and supplied to universal asynchronous transceiver (UART) for setting the detected data communication characteristic. An Independent claim is also included for data communication characteristic detection device.
