A byte offset (from 0) which points to the location in DMA receive buffer B where the next byte
will be placed. When the buffer fills and subsequently unloads, this register wraps around and
holds the value zero (pointing back to the first location in the buffer).
A byte offset (from 0) which points to the location in the active (loaded) DMA transmit buffer
where the next byte will be placed. When the buffer fills and subsequently unloads, this regis-
ter wraps around and holds the value zero (pointing back to the first location in the buffer).
DMA Start address (byte aligned) for receive buffer A.
DMA End address (byte aligned) for receive buffer A.
