2. GENERAL DESCRIPTIONS

The MX98715AEC-C controller is an IEEE802.3u com-

pliant single chip 32-bit full duplex, 10/100Mbps highly

integrated Fast Ethernet combo solution, designed to

address high performance local area networking (LAN)

system application requirements.

MX98715AEC-C's PCI bus master architecture delivers

the optimized performance for future high speed and pow-

erful processor technologies. In other words, the

MX98715AEC-C not only keeps CPU utilization low while

maximizing data throughput, but it also optimizes the

PCI bandwidth providing the highest PCI bandwidth uti-

lization. To further reduce maintenance costs the

MX98715AEC-C uses drivers that are backward com-

patible with the original MXIC MX98713 series control-

lers.

The MX98715AEC-C contains a PCI local bus glueless

interface, a Direct Memory Access (DMA) buffer man-

agement unit, an IEEE802.3u-compliant Media Access

Controller (MAC), large T ransmit 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-duple x oper ation 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-

negotiation, the MX98715AEC-C-based adapter allows

a single RJ-45 connector to link with the other

IEEE802.3u-compliant device without re-configuration.

In MX98715AEC-C, an innovative and proprietary de-

sign "Adaptive Netw ork Throughput Control" (ANTC) is

built-in to configure itself automatically by MXIC's driver

based on the PCI burst throughput of diff erent PCs. With

this proprietary design, MX98715AEC-C can always

optimize its operating bandwidth, network data integrity

and throughput for different PCs.

The MX98715AEC-C features Remote-Power-On and Re-

mote-W ake-Up capability and is compliant with the Ad-

vanced Configuration and Power Interface version 1.0

3. PIN CONFIGURATIONS

(A CPI). This support enab les a wide range of wak e-up

capabilities, including the ability to customize the con-

tent of specified packet which PC should be responded

to , e ven when it is in a lo w-power state. PCs and w ork-

stations could take advantage of these capabilities of

being waked up and served simultaneously over the net-

work by remote server or workstation. It helps organi-

zations reduce their maintenance cost of PC network.

The 32-bit multiplexed bus interface unit of

MX98715AEC-C provides a direct interface to a PCI lo-

cal bus, simplifing the design of an Ethernet adapter in a

PC system. With its on-chip support for both little and

big endian byte alignment, MX98715AEC-C can also

address non-PC applications.

5.3 A CPI Power Management Support

The Advanced Configuration and Power Interface (ACPI)

Specification defines a flexible and abstract fardware

interface for a wide varity of PC systems to implement

pow er and thernal management functions . This chip is

fully compliant with the OnNow Network Device Class

P ower Management spec. rec.1.0, the PCI power man-

agement interface spec. rev.1.0 and the ACPI spec.

rev.1.0.

F our po wer states defined f or a PCI function are:

* D0-Fully On.

The device is completely active and respon-

sive.

* D1-Light Sleep.

Save a little power than D0 state. The PCI

clock is running.

* D2-Deeper Sleep:

Save more power than D1 state. The PCI clock

can be stopped.

* D3hot-Deepest Sleep:

Save more power than D2 state. The PCI clock

is stopped.

* D3cold-P o wer Do wn:

In this state, the main system power is

removedfrom the chip but will preserve their

PME context when transitioning from the D3cold

to the D0 state. Such function requires an

auxiliar y power source other than main sys-

tem pow er plane.

This chip also supports the OnNow Network Device

Class Specification based on the ACPI specification

defines the power management requirements of a net-

work de vice . It defines the following wake-up e vents:

* Reception of a Magic P ac k et.

* Reception of a Network wake-up frame.

* Detection of change in the network link state.

To put MX98715/725 into the sleep mode and enable

the wak e-up e vents detection are done as follo wing:

1. Write 1 to PPMCSR[8] to enable power management

feature.

2. Write the v alue to PPMCSR[1:0] to determine which

pow er state to enter.

If D1, D2 or D3hot state is set, the PC is still turned on

and is commonly called entering the Remote Wake-up

mode. Otherwise if the main power on a PC is totally

shut off, we call that it is in the D3cold state or Remote

Power-On mode. To sustain the operation of the Lan

card, a 5V standby power is required. Once the PC is

turned on, MX98715/725 loads the Magic ID from

EEPROM and set it up automatically. No registers is

needed to be programmed. After then, simply turn of

PC to enter D3cold state. In either Remote Wake-up mode

or Remote Power-On mode. The transceiver and the

RX bloc k are still alive to monitor the network activity. If

one of the three wak e-up e vents occured, the f ollo wing

status is changed:

1. PPMCSR[15] (PME status) is set to 1.

2. CRS5[28] (WKUPI) is set to 1.

3. PCI interrupt pin INTA# is asserted low.

4. PMEB pin is asserted lo w.

5. In MX98725, EXTSTARTB and LANWAKE are also

asserted.

5.3.1 Magic P ac ket

The Magic Pack et(TM) technology, proposed by AMD, is

used to remotely wak e up a sleeping or powered off PC

on a network. This is accomplished by sending a spe-

cific pack et, called Magic Pack et, to a node on the net-

work. When a NIC capable of recognizing the specific

frame goes to sleep (entering D1, D2 ro D3 state), it

scans all incoming frames addressed to the node for a

specific data sequence, which indicates to the control-

ler that this is a Magic Packet frame. The specific se-

quence consists of 16 duplications of the IEEE address

of this node, with no breaks or interruptions. This se-

quence can be located anywhere within the pac ket, but

must be preceded by a synchronization stream. The

synchronization stream is defined as 6 bytes of FFh.

For example, if the IEEE address for a particular node

on the network was 11h 22h 33h 44h 55h 66h, then the

Magic Packet for this node would be:

D A SA MISC. FF FF FF FF FF FF 11 22 33 44 55 66 11

22 33 44 55 66 11 22 33 44 55 66 11 22 33 44 55 66

11 22 33 44 55 66 11 22 33 44 55 66 11 22 33 44 55 66

MISC . CRC.

P/N:PM0655 REV. 0.3, MAY. 04, 2000

MX98715AEC-C

This chip can automatically loads the IEEE address into

the internal registers from EEPROM while booting up.

the magic packet detection scheme is not active while

chip is in normal running state (D0). After entering into

the sleep mode(D1, D2, D3) b y host, the chip begins to

scan the incoming pack et b ut does not load the pac ket

into RX FIFO . If a magic pack et is detected, the PMEB

is asserted to notify the host.

Magic packet event occurs when the following condi-

tions are approv ed:

* The destination address of the received packet

matches.

* The PMEN bit (PPMCSR[8]) is set to 1.

* Not in D0 state.

* The magic packet pattern matches, i.e., 6*FFh +

16* Destination ID .

<Note>: The CRC value is not checked during magic

pack et detection.

5.3.2 Wake-up Frames

A network wake-up frame is typically a frame that is

sent by existing network protocols, such as ARP re-

quests or IP frames addressed to the machine. Before

putting the network adapter into the wake-up state , the

system passes to the adapter's driver a list of sample

frames and corresponding byte masks. Each sample

frame is an e xample of a frame that should wake up the

system. Each byte mask defines which bytes of the

incoming frames should be compared with correspond-

ing sample frame in order to determine whether or not

to accept the incoming frame as a wake-up e v ent.

The on-chip Wake-up logic prevides four programmable

filters that allow support of many different receive packet

patterns. Specifically, these filters allow suppor t of IP

and IPX protocols which currently are the only proto-

cols targeted to be power manageable. Each filter re-

lates to 32 contiguous bytes in the incoming fr ame.

When a frame is received from the network, the chip

examines its content to determine whether the pattern

matches to a wake-up frame. To know which byte of the

frame should be checked, a programmable byte-mask

and a programmable patter n offset are used for each

one of the f our supported filters. The pattern offset de-

fines the location of the first byte in the frame that should

be check ed. Beginning with the pattern offset, if bit j in

the byte mask is set, byte offset+j in the frame is

checked.

The chip implements imperfect pattern matching by

calculating a CRC-16 on all bytes of the receiv ed frame

that where specified by the pattern's offset and the byte

mask and comparing to a programmable pre-calculated

CRC-16 remainder value. The CRC calculation uses

the f ollowing polynomial:

G(X)=X16 + X15 + X2 +1

The calculated CRC-16 value is compared with four

possible CRC-16 v alues stored in CSR30 and CSR31.

if the result matches any one and the enable bit of the

corresponding filter also set, then we call a Wakeup

frame receiv ed.

Table1 shows the wake-up frame register block. This

b lock is accessed through CSR registers mapping.

Filter 0 Byte Mask CSR25

Filter 1 Byte Mask CSR26

Filter 2 Byte Mask CSR27

Filter 3 Byte Mask CSR28

Filter 3 Filter 2 Filter 1 Filter 0 CSR29

Filter 1 CRC-16 Filter 0 CRC-16 CSR30

Filter 3 CRC-16 Filter 2 CRC-16 CSR31

The four filters can operate independently to match four

32-byte wake up frames. They also can be programmed

to catenate each other to support longer wake up frames,

ranging from 32 bytes up to 128 bytes. The following

table sho ws the possible combination.

CSR21.4 CSR9.26 CSR9.25 Wake up event

WKFCATEN WKFCAT1 WKFCAT0

0 X X CH0+CH1+CH2+CH3

1 0 0 (CH0.CH1)+(CH2.CH3)

1 0 1 (CH0.CH1)+CH2+CH3

1 1 0 (CH0.CH1.CH2)+CH3

1 1 1 CH0.CH1.CH2.CH3

If WAKCATEN (CSR21.4) is not set, the f our filters are

independent and simultaneous to match the incoming

frame. When WKFCATEN is set, the catenation options

are determined by WKFCAT<1:0> (CSR<26:25>). For

example, if WKFCAT<1:0>=00, wake up event is oc-

curred only if either both of channel 0 and channel 1

match or both of channel 2 and channel 3 match. If the

* Not in D0 state.

* The destination address of the received wakeup

frame matches.

* No CRC-32 error is detected in the wakeup fr ame.

* The PMEN bit (PPMCSR[8]) is set to 1.

* The enable bit in the wakeup frame register block

must be set.

* The CRC value calculated from the bytes in the

pre-designated locations equals to the respectively

stored CRC-16 value .

* If catenation must be met. enable bit WKFCATEN

is set, the condition in table 2.

5.3.3 Link Change

Link change wakeup event occurs when the following

conditions are met:

* Not in D0 state.

* The PMEN bit (PMCSR[8]) is set to 1.

* The cable is re-connected.

The Remote Power-on (RPO) feature is a mechanism

can be used to remotely power up a sleeping station.

When the PC turned on, MX98715AEC-C loads the net-

work ID from serial ROM automatically. Once the PC is

turnned off, MX98715AEC-C enters the RPO mode.

MX98715AEC-C monitors the network for receipt of a

wakeup packet. If a magic packet or wake up frame is

received, it asserts LANWAKE, signal to wake up the

system. After main power is on, LANWAKE is deasserted

by PCI RSTB signal. After the deassertion,

MX98715AEC-C can enter RPO mode again if the main

power is switched off.

driver sets filter 0 and filter 1 be contiguous and also

sets filter 2 and filter 3 be contiguous by adjusting the

offsets, then two 64-byte wake up frames are supported.

Another example is that if WKFCAT<1:0>=11 and the

driver sets filter 0,1,2,3 as contiguous, a 128-byte wake

up frame is supported.

Wakeup Frames event occurs when following conditions

are met:
