The target data may be used to indicate data to be read/written in the Flash storage module. The start address may be used to indicate an address at which read/write operations are to be started on target data in the Flash memory module. The operation byte number can be used for indicating the byte number corresponding to the target data.
In specific implementation, under the condition that a DMA mode is used to perform read-write operation on a Flash memory module, before a target array pointer, a start address and an operation byte number corresponding to target data are obtained, multi-line related SPI setting and multi-line read-write command switching need to be set.
Therefore, the micro control unit can perform read operation or write operation on the Flash storage module according to the target configuration, the target array pointer, the starting address and the number of operation bytes, and is favorable for improving the read-write rate of the Flash storage module.

The second status check information may be used to indicate that the id is wrong.
The preset identity identification library can be stored in the micro control unit in advance. The identity library can store the identity corresponding to each Flash storage module.
In the specific implementation, whether the Flash storage module currently communicating with the micro control unit is registered in the micro control unit in advance can be determined through the identity of the Flash storage module. If the identity exists in the preset identity library, that is, if the Flash storage module currently communicating with the micro control unit is registered in the micro control unit in advance, the step of acquiring the first configuration information of the Flash storage module is further executed. If the preset identity identification library does not have the identity identification, second state checking information is generated, and a user can know that the current running state of the micro control unit is that the Flash storage module is not registered in advance according to the second state checking information.
It can be seen that, in the embodiment of the present application, an identity of a Flash storage module is obtained, where the identity is used to represent registration information of the Flash storage module in a micro control unit, and when the identity exists in a preset identity library, first configuration information of the Flash storage module and second configuration information of an OTP storage module are obtained, and when the identity does not exist in the preset identity library, second status check information is generated, and the second status check information is used to indicate that the identity is wrong; therefore, the registration information of the Flash storage module in the micro control unit is determined through the identity identification, and whether the first configuration information is acquired or not is determined according to the registration information, so that the stability of the Flash storage module in operation is improved, the data stored in the Flash storage module is not easy to lose, the stability of the Flash storage module in operation is ensured in data safety, and the data safety is ensured.
