1. a kind of reference frequency setting method of type nonvolatile storage device, the wherein duplicative are non-easilyThe property lost memory storage apparatus includes a reproducible nonvolatile memorizer module, a storage unit and an oscillating circuit mouldBlock, the oscillating circuit module include a register circuit, which does not include a stoneEnglish oscillator, the reference frequency setting method include:

  • Using one first signaling path one is read out of the reproducible nonvolatile memorizer module or the storage unitCode is set, and the setting code is stored in the register circuit, wherein the setting code includes one first set information;

    Whether the data for detecting a first frequency are transfused to;

    If the data of the first frequency are not transfused to, the setting code being stored in the register circuit is read, so that shouldOscillating circuit module produces one first reference frequency according to first set information of the setting code;

    If the data of the first frequency are transfused to, updated storage using a secondary signal bang path in the register circuitInterior setting code, wherein the setting code after renewal includes one second set information;

    AndIf the data of the first frequency are transfused to, reading is stored in the setting code after the renewal in the register circuit, withMake the oscillating circuit module according to second set information to produce one second reference frequency.
