AjK 1:9700b9455cbf 199 * <b>MODDMA</b> defines a GPDMA controller and multiple DMA configurations that allow for DMA
AjK 0:c409efd8df78 200 * transfers from memory to memory, memory to peripheral or peripheral to memory.
AjK 1:9700b9455cbf 201 *
AjK 3:f61c089ca882 202 * At the heart of the library is the MODDMA class that defines a single instance controller that
AjK 1:9700b9455cbf 203 * manages all the GPDMA hardware registers and interrupts. The controller can accept multiple
AjK 3:f61c089ca882 204 * configurations that define the channel transfers. Each configuration specifies the source and
AjK 3:f61c089ca882 205 * destination information and other associated parts to maintain the transfer process.
AjK 1:9700b9455cbf 206 *
