2. GENERAL DESCRIPTIONS
The MX98715EC controller is an IEEE802.3u compliant
single chip 32-bit full duplex, 10/100Mbps highly inte-
grated Fast Ether net combo solution, designed to ad-
dress high performance local area networking (LAN)
system application requirements.
MX98715EC's PCI bus master architecture delivers the
utilimized perfor mance for future high speed and pow-
erful processor technologies. In other words, the
MX98715EC not only keeps CPU utilization low while
maximizing data throughput, but it also optimizes the
PCI bandwidth providing the highest PCI bandwidth utili-
zation. To further reduce maintenance costs the
MX98715EC uses drivers that are backward compatible
with the original MXIC MX98713 series controllers.
The MX98715EC contains a PCI local bus glueless in-
terface, a Direct Memory Access (DMA) buffer manage-
ment unit, an IEEE802.3u-compliant Media Access Con-
troller (MAC), large Transmit and Receive FIFOs, and
an on-chip 10 Base-T and 100 Base-TX transceiver sim-
plifying system design and improving high speed signal
quality. Full-duplex operation are supported in both 10
Base-T and 100 Base-TX modes that increases the
controller's operating bandwidth up to 200Mbps.
Equipped with intelligent IEEE802.3u-compliant auto-ne-
gotiation, the MX98715EC-based adapter allows a single
RJ-45 connector to link with the other IEEE802.3u-com-
pliant device without re-configur ation.
In MX98715EC, an innovative and proprietary design
"Adaptive Network Throughput Control" (ANTC) is built-
in to configure itself automatically by MXIC's driver based
on the PCI burst throughput of different PCs. With this
proprietary design, MX98715EC can always optimize its
operating bandwidth, network data integrity and through-
put for different PCs.
MXIC MX98715EC features Remote-Wake-Up capabil-
ity that enables a wide range of wake-up capabilities,
including the ability to customize the content of speci-
fied packet which PC should to respend to, e ven when it
is in a low-power state. PCs and workstations could
take advantage of these capabilities of being waked up
and serviced simultaneiously over the network by remote
server or workstation. It helps organizations reduce their
maintenance cost of high-perfor mance business PCs.
With its on-chip support for both little and big endian
byte alignment, MX98715EC can also address non-PC
applications.

Field Name Description
10 ETI Early Transmit Interrupt, indicating the packet to be transmitted was fully transferred to
internal TX FIFO. CSR5<0> will automatically clears this bit.
9 RWT Receive Watchdog Timeout, reflects the network line status where receive watchdog timer
has e xpired while the other node is still activ e on the network.
8 RP S Write only, when written with any v alue, MX98715EC reads receiv e descriptor list in host
memory pointed by CSR4 and processes the list.
7 R U Receive Buffer Unavailable , the receiv e process is suspended due to the ne xt descriptor
in the receive list is owned by host. If no receive poll command is issued, the reception
process resumes when the ne xt recogniz ed incoming fr ame is received.
6 RI Receive Interrupt, indicating the completion of a frame reception.
5 UNF Transmit Underflow, indicating transmit FIFO has run empty before the completion of a
pack et transmission.
4 LPANCI When autonegotiation is not enabled ( CSR14<7>=0 ), this bit indicates that the 10 Base-
T link integrity test has completed successfully, after the link was do wn. This bit is also set
as as a result of writing 0 to CSR14<12> ( Link Test Enable ).
When Autonegotiation is enabled ( CSR14<7> =1 ) , this bit indicates that the autonegotiation
has completed ( CSR12<14:12>=5 ). CSR12 should then be read for a link status report.
This bit is only v alid when CSR6<18>=0, i.e. 10 Base-T port is selected Link F ail interrupt
( CSR5<12> ) will automatically clears this bit.
3 TJT Transmit Jabber Timeout, indicating the MX98715EC has been excessively active. The
transmit process is aborted and placed in the stopped state. TDES0<1> is also set.
2 TU Transmit Buff er Unavailable , transmit process is suspended due to the ne xt descriptor in
the transmit list is o wned b y host.
1 TPS Transmit Process Stopped.
