To use linking, write the address of the the first linked descriptor to this register. When a linked descriptor is loaded, it may
also be linked to another descriptor. Reading this register will reflect the address of the next linked descriptor.
1 LINK
After completing the initial transfer, if this bit is set, the DMA will load the next linked descriptor. If the next linked descriptor
also has this bit set, the DMA will load the next linked descriptor.
0 LINKMODE
This field specifies the addressing mode of linked descriptors. After loading a linked descriptor, reading this field will indi-
cate the addressing mode of the loaded linked descriptor. Note that the first descriptor always uses absolute addressing
mode.
