| /// !Purpose | |
| /// | |
| /// Interface for configuration the %DMA controller(DMAC). | |
| /// | |
| /// !Usage | |
| /// | |
| /// -# Enable or disable the a DMAC controller with | |
| /// DMA_Enable() and or DMA_Disable(). | |
| /// -# Enable or disable %Dma interrupt using DMA_EnableIt() | |
| /// or DMA_DisableIt(). | |
| /// -# Get %Dma interrupt status by DMA_GetStatus(). | |
| /// -# Enable or disable specified %Dma channel with | |
| /// DMA_EnableChannel() or DMA_DisableChannel(). | |
| /// -# Get %Dma channel status by DMA_GetChannelStatus(). | |
| /// -# Configure source and/or destination start address with | |
| /// DMA_SetSourceAddr() and/or DMA_SetDestAddr(). | |
| /// -# Set %Dma descriptor address using DMA_SetDescriptorAddr(). | |
| /// -# Set source transfer buffer size with DMA_SetSourceBufferSize(). | |
| /// -# Configure source and/or destination transfer mode with | |
| /// DMA_SetSourceBufferMode() and/or DMA_SetDestBufferMode(). | |
| /// -# Configure source and/or destination Picture-In-Picutre | |
| /// mode with DMA_SPIPconfiguration() and/or DMA_DPIPconfiguration(). | |
