10 The STM32 MDMA is a general-purpose direct memory access controller capable of
13 described in the dma.txt file, using a five-cell specifier for each channel:
22 -bit 0-1: Source increment mode
26 -bit 2-3: Destination increment mode
30 -bit 8-9: Source increment offset size
32 0x1: half-word (16bit)
