Description: This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data bufferstored as constant in the Flash memory to another buffer in the RAM memory.The received data are stored in the DST_Buffer.The DMA channel transfer complete interrupt is enabled to generate an interrupt atthe end of the buffer transfer. As soon as the transfer is completed an interrupt isgenerated and in the DMA channel interrupt routine the transfer complete interrupt pending bit is cleared. The data counter is stored before and after the transfer to show that all data has beentransfered.TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED
