Function
Destination start address, upper bits
Destination start address, upper bits
-
Upper bits for the source start address, expressed in bytes. The destina-
tion start address is made of the concatenation of DMA_CDSA_U and
DMA_CDSA_L.
Function
Channel element number
Element number
-
Number of elements within a frame (unsigned). The maximum element
number is 65535.
Function
Channel frame number
Frame number
-
Number of frames within the block to be transferred (unsigned). The maxi-
mum frame number is 65535.
The size in bytes of the data block to transfer is data_block_in_bytes =
DMA_CFN x DMA_CEN x DMA_CSDP[data_type].
