5.6.11 Receive DMA Address Registers A, B

There are two sets of Receive DMA Address Registers, one set for Receive DMA Channel
A and one set for Receive DMA Channel B. Each set consists of four registers, one for
address bits 7-0, one for address bits 15-8, one for address bits 23-16, and one for address
bits 31-24 as shown in Figure 5-36. These registers are read/write.
