transfer takes place this register is decremented by one. When the transfer length 
decrements to zero, the buffer is complete and the DMA either stops or loads new control 
information and addresses (see the Linked List description that follows).
List Address Register
The list address register (LAR) is only used for linked list mode. The LAR points to a list
of descriptors (described below). This descriptor list contains setup information for each
buffer the DMA is to transfer. Linked list DMAs reduce the amount of overhead on the
CPU to service the DMA.
Descriptor
A Descriptor is a 16 byte field in the memory space. It needs to be aligned on 16 byte
boundaries (that is lower 4-bits of address is 0). Table 120 provides the descriptor format.
