Please refer to * the reference manual for further details. The LDMA examples described * in the reference manual are particularly helpful in understanding LDMA * operations. * * In order to use the DMA controller, the initialization function @ref * LDMA_Init() must have been executed once (normally during system init). * * DMA transfers are initiated by a call to @ref LDMA_StartTransfer(), the * transfer properties are controlled by the contents of @ref LDMA_TransferCfg_t * and @ref LDMA_Descriptor_t structure parameters. * The @htmlonly LDMA_Descriptor_t @endhtmlonly structure parameter may be a * pointer to an array of descriptors, the descriptors in the array should * be linked together as needed. * * Transfer and descriptor initialization macros are provided for the most common * transfer types. Due to the flexibility of the LDMA peripheral only a small * subset of all possible initializer macros are provided, the user should create * new one's when needed. * * <b> Examples of LDMA usage: </b> * * A simple memory to memory transfer: * * @include em_ldma_single.c * * @n A linked list of three memory to memory transfers: * * @include em_ldma_link_memory.c * * @n DMA from serial port peripheral to memory: * * @include em_ldma_peripheral.c * * @n Ping pong DMA from serial port peripheral to memory: * * @include em_ldma_pingpong.c * * @note The LDMA module does not implement the LDMA interrupt handler. A * template for an LDMA IRQ handler is include here as an example. * * @include em_ldma_irq.c * * @{ ******************************************************************************/
