| 摘要 |
It is described a method for operating a communication system comprising a first device with a working oscillator and a second device with a reference oscillator, the method comprising calibrating the working oscillator of the first device connected to an asynchronous serial communications bus, calibrating comprising defining a measurement time T A , measuring and selecting a predefined pulse space T 1 of a first signal formed by a plurality of predefined discrete pulse spaces and generated by a second device comprising a reference oscillator and received by said first device during T A over said asynchronous serial communications bus. |
