Description
Upper bits for the source start address, expressed in
bytes. The destination start address is made of the
concatenation of DMA_CDSA_U and DMA_CDSA_L.
Description
Number of elements within a frame. The maximum
element number is 65535.
Description
Number of frames within the block to transfer. The
maximum frame number is 65535.
The size in bytes of the data block to transfer is
DMA_CFN x DMA_CEN x DMA_CES. This size is
programmed in bytes to:
-
Allow transfer of an odd byte number
-
Accommodate the requirement of different access
sizes on source and destination ports
Description
Contains the frame index, expressed in bytes, used to
compute the addresses when double-index addressing
mode is used.
