Peripheral interface time sequence parameter self-adaptive adjusting method and time sequence parameter adjusting device

The invention relates to a peripheral interface time sequence parameter self-adaptive adjustment method and a time sequence parameter adjustment device, and the method comprises the steps: carrying out the self-adaptive adjustment of an interface time sequence parameter of an external part according to an initialization signal of the external part and a preset adjustment step, the preset adjustment step sequentially comprises the steps of adjusting the interface time sequence parameter according to a preset time sequence parameter value, adjusting the interface time sequence parameter by adjusting an establishment time parameter value in the time sequence parameter value, and adjusting the interface time sequence parameter by adjusting a retention time parameter value in the time sequence parameter value. And when the interface time sequence parameter is adjusted according to a preset adjustment step, performing a data read-write operation under the interface time sequence parameter obtained after the adjustm
