Realization method of real-time clock self clocking

The invention relates to the field of the embedded information. The real-time clock self clocking method in the prior art has high power consumption, and the system anti-jamming signal capability is low, the system stability is low and the method has poor adaptability. Therefore, the invention provides a technical scheme of a new real-time clock self clocking method, According to the technical scheme, an unlocking state linear shift register, a detection linear shift register as long as the unlocking state linear shift register and one set of operation programs matched with the unlocking state linear shift register are added in an RTC (Real-Time Clock) self-locking circuit. The technical scheme achieves the purpose of the invention and has the following beneficial effects that system stability is high, the accuracy and the lower power consumption of a clock are guaranteed, an IP (Intellectual Property) module is multiplexed, the development time is shortened, and the adaptability is improved.
