In order to make the present invention obvious and easy to understand, a detailed description is given below as follows: The description of the embodiments and other preferred embodiments of the present invention can be further characterized, and the features, and advantages can be further improved. A flowchart of an embodiment of the present invention. The present invention uses the real time clock (RTC) method of the next day, clock method to measure the frequency of the real-time clock oscillator generated by the game oscillator, step S01; To generate a real-time clock without error, consider the oscillator Fnonnal and the total number of seconds Ts d in a day (the normal oscillation frequency of step ^ is 32.768 kHz to produce the time),-General: Oscillation frequency ^ [… ^, And one day two two ^ so the normal vibration surplus frequency # X, the county is ancient. The total number of seconds is 86400 seconds. Then, based on the normal oscillation frequency Fn_al and the stomach stomach F_ure for one day, calculate the corresponding error time T (step, step, and measurement frequency $ plug H, helmet-worker), and take step S103. Here, In the embodiment, the difference between the day and the day Te is the number of seconds of the clock error between the mother and the day, where

For example, when measuring the measuring frequency FA of the oscillator, the error time Te is 5 · 2734375 seconds, which is 2.2 · 5.2734375 seconds'. But because the digital circuit is: The second mother will quickly process numbers with high accuracy in one day, so the time limit / :, cannot store # (5. 2734375) stored in flash memory, so, Ding method / also connect this value Π so It can be stored in flash memory 575801. 5. Description of the invention (3) Set to reduce 5 seconds every day to improve that by subtracting one second every 3 days, or 6 seconds, to calibrate the block difference, and accurately describe the difference in the mother. The problem of insufficient degree. , T, and ′ are fine-tuned to solve the problem. It should be noted that the error time is stored in the example of the present invention, but the present invention can also use the flash memory as the error time.

The first Ώ Ί τ-ρ only + Real Time Clock (RTC) generated by Zhenlu Yi in the method of the present invention.

Then, the error time Te is stored in the flash memory (step S204). Finally, the error is taken out of the flash memory at the preset time, and the real-time clock is calibrated with the error time (step S205). For example, when the measurement frequency Fme_re of the measurement oscillator is 32.77. At kHz, if the preset time is four days, the error time Te is 21019375 seconds, which means that it will be 2 1 · 0 9 3 7 5 seconds every four days, but due to the limitation of digital circuit processing, it cannot be stored and Handling numbers with too high a precision, so you cannot directly &
