DM9102A
Single Chip Fast Ethernet NIC controller
This bit is set when the DM9102A fetches the next transmit descriptor that is still
owned by the host. Transmit process will be suspended until the transmit polling
command is set or auto-polling timer time-out.

Transmit Process Stopped
This bit is set to indicate transmit process enters the stopped state.

TXCI
0,RW
Transmit Complete Interrupt
This bit is set when a frame is fully transmitted and transmit status has been written to
descriptor (the TDES1<31> is also asserted). Transmit process is still running and
continues to fetch next descriptor.

Description
Receive All
When set, all incoming packet will be received, regardless the destination address.
The address match is checked according to theCR6<7>, CR6<6>, CR6<4>,
CR6<2>, CR6<0>, and RDES0<30> will show this match.
Set to not purge RX FIFO if RX buffer unavailable
Must be Zero
Must be One
Must be Zero
Transmit Threshold Mode
When set, the transmit threshold mode is 10Mb/s. When reset, the threshold mode
is 100Mb/s. This bit is used together with CR6<15:14> to decide the exact
threshold level.
Store and Forward Transmit
When set, the packet transmission from MAC will be started after a full frame has
been moved from the host memory to transmit FIFO. When reset, the packet
transmission’s start will depend on the threshold value specified in CR6<15:14>
Start Transmission Immediately
When this bit is set, the packet transmission from MAC will be started immediately
after transmit FIFO’s threshold level reaches 16 bytes, regardless of the setting in
CR6<22> and CR6<15:14>. This mode will make transmit FIFO underrun
condition to happen more easily.
Reserved
1: Select external MII interface.
0: Select external SRL interface.
In external MII mode that the pins TEST1, TEST2, and CLOCKRUN# are forced to
low, the DM9102A bypasses internal PHY and uses external PHY, by setting this
bit properly.
See page 66 for details.
Reserved
One Packet Mode
When this bit is set, only one packet is stored at TX FIFO.
