- * @brief DMA Extension HAL module driver
- * This file provides firmware functions to manage the following
- * functionalities of the DMA Extension peripheral:
- * + Extended features functions
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The DMA Extension HAL driver can be used as follows:
- (#) Start a multi buffer transfer using the HAL_DMA_MultiBufferStart() function
- for polling mode or HAL_DMA_MultiBufferStart_IT() for interrupt mode.
-
- -@- In Memory-to-Memory transfer mode, Multi (Double) Buffer mode is not allowed.
- -@- When Multi (Double) Buffer mode is enabled the, transfer is circular by default.
- -@- In Multi (Double) buffer mode, it is possible to update the base address for
- the AHB memory port on the fly (DMA_SxM0AR or DMA_SxM1AR) when the stream is enabled.
