[0054] Example
[0055] Figure 7 It is a schematic diagram of the composition structure of the frequency adjustment device according to the embodiment of the present invention. Such as Figure 7 As shown, in this embodiment, the frequency adjustment device includes a microprocessor, a first register, a D flip-flop, a comparator, a second register, a third register, a counter, a frequency divider, an enable signal generation module, and an AND gate. ; Among them, the D flip-flop will read the first frequency division coefficient from the first register, and delay the first frequency division signal containing the first frequency division coefficient by one main clock cycle to obtain the second frequency division coefficient containing the second frequency Frequency division signal. The third register stores the preset first threshold and second threshold, and the first threshold is preset to 16 and the second threshold is 32. The frequency division coefficient before resetting se...
