Detailed Description
Initialization and de-initialization functions.
===============================================================================
##### Initialization and de-initialization functions #####
===============================================================================
[..]
This section provides functions allowing to initialize the DMA Channel source
and destination addresses, incrementation and data sizes, transfer direction,
circular/normal mode selection, memory-to-memory mode selection and Channel priority value.
