Note: All examples above will result in a transmission of a packet in order of DA0 (Destination Address 0),
DA1, DA2, DA3 . . . in byte. Bits within each byte will be transmitted least significant bit first.
The Remote DMA channel is used to both assemble packets for transmission, and to remove received packets
from the Receive Buffer Ring. It may also be used as a general purpose slave DMA channel for moving blocks
4.2.3 Filling Packet to Transmit Buffer (Host fill data to memory)
