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 buffer stored 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 at the end of the buffer transfer. As soon as the transfer is completed an interrupt is generated 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 been transfered. TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED

D169 Demo - DMA0 Repeated Burst to-from RAM, Software Trigger Description A 32 byte block from 220h-240h is transfered to 240h-260h using DMA0 in a burst block using software DMAREQ trigger. After each transfer, source, destination and DMA size are reset to inital software setting because DMA transfer mode 5 is used. P1.0 is toggled durring DMA transfer only for demonstration purposes. ** RAM location 0x220 - 0x260 used - always make sure no compiler conflict ** ACLK= n/a, MCLK= SMCLK= default DCO ~ 800k
