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.
4.2.3 Filling Packet to Transmit Buffer (Host fill data to memory)
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
of data or commands between host memory and local buffer memory. There are two modes of operation, Remote
Write and Remote Read Packet.
Two register pairs are used to control the Remote DMA, a Remote Start Address (RSAR0, RSAR1) and a
Remote Byte Count (RBCR0, RBCR1) register pair. The Start Address Register pair points to the beginning of
the block to be moved while the Byte Count Register pair is used to indicate the number of bytes to be
transferred. Full handshake logic is provided to move data between local buffer memory (Embedded Memory)
and a bidirectional I/O port.
BOS = 0, WTS = 0 in Data Configuration Register.
This format is used with ISA, 80186 or MCS-51 Mode.
