* @brief Linked Direct Memory Access (LDMA) Peripheral API
*
* @details
* LDMA API functions provide full support for the LDMA peripheral.
*
* LDMA supports these DMA transfer types:
*
* @li Memory to memory.
* @li Memory to peripheral.
* @li Peripheral to memory.
* @li Peripheral to peripheral.
* @li Constant value to memory.
*
* LDMA supports linked lists of DMA descriptors allowing:
*
* @li Circular and ping-pong buffer transfers.
* @li Scatter-gather transfers.
* @li Looped transfers.
*
* LDMA has some advanced features:
*
* @li Intra-channel synchronization (SYNC), allowing hardware events to
* pause and restart a DMA sequence.
* @li Immediate-write (WRI), allowing DMA to write a constant anywhere
* in the memory map.
* @li Complex flow control allowing if-else constructs.
*
* Basic understanding of LDMA controller is assumed. 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 initialization).
*
* DMA transfers are initiated by a call to @ref LDMA_StartTransfer(),
* 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, descriptors in 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 LDMA peripheral, only a small
* subset of all possible initializer macros are provided, users should create
* new ones 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 LDMA module does not implement LDMA interrupt handler. A
* template for an LDMA IRQ handler is included here as an example.
*
* @include em_ldma_irq.c
