It is assumed that the SFRs used by this library are in their reset state.4.3 GetVersionOfDrive

7、rIO_U32 GetVersionOfDriver（void） This is the getting driver version function of the ADC function library. It is assumed that the SFRs used by this library are in their reset state.4.4 ADC0_StartSampleSyncIO_ErrorType ADC0_StartSampleSync（ubyte Channels） ADC0_StartSampleSync was successful.This funct
