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 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

Description: 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.
