Link Street® 88E6060 - Unrestricted
Low Power, 6-port, 10/100 Ethernet Switch
Overview
Features
The Marvell® 88E6060 is a single chip integration of a
complete 6-port Fast Ethernet switch with support for a
CPU connection. It contains five 10BASE-T/100BASETX transceivers (PHYs), two that can be used to support 100BASE-FX; six independent Fast Ethernet
media access controllers (MACs), a high-speed nonblocking switch fabric, a high-performance address
lookup engine, and a 1/2 megabit frame buffer memory. It is designed for cost-sensitive low port count
switch systems and firewall routers.
•
The PHY transceivers are designed with Marvell Virtual Cable Tester™ (VCT™) technology for advanced
cable diagnostics. VCT enables IT managers to easily
pinpoint the location of cabling issues down to a meter
or less, reducing network installation and support
costs.
The Marvell 88E6060 is designed to work in all environments. True Plug-n-Play is supported with Auto
Crossover, Auto Polarity and Auto Negotiation in the
PHYs, along with bridge loop prevention (using Port
States implementing Spanning Tree support).
The shared memory-based switch fabric uses the latest Marvell switch architecture that provides nonblocking switching performance in all traffic environments. Back-pressure and pause-frame-based flow
control schemes are included to support zero packet
loss under temporary traffic congestion. The lookup
engine allows for up to 1,024 active nodes to be connected with the switch.
The sixth port, ‘always-on’ RMII/MII/SNI interface supports a direct connection to Management or Router
CPUs with integrated MACs. It can be configured in
either RMII mode, MII-PHY or MII-MAC mode or SNI
mode. These interfaces along with BPDU handling,
programmable per port VLAN configurations, and Port
States, support Spanning Tree and truly isolated WAN
vs. LAN firewall applications.
The PHY units in the Marvell 88E6060 are designed
with Marvell cutting-edge mixed-signal processing
technology for digital implementation of adaptive
equalization and clock data recovery. Special power
management techniques are used to facilitate low
power dissipation and high port count integration. Both
the PHY and MAC units in the Marvell 88E6060 comply fully with the applicable sections of IEEE 802.3,
IEEE 802.3u, and IEEE 802.3x standards.
The many operating modes of the Marvell 88E6060
can be configured using SMI (serial management
interface - MDC/MDIO) and/or a low cost serial
EEPROM (93C46, C56 or C66).

XTAL_IN
Input
25 MHz or 50 MHz system reference clock input. The frequency of this clock input is selected by the CLK_SEL pin.
The clock source can come from a crystal (25 MHz only) or an
oscillator (25 or 50 MHz). This is the only clock required as it
is used for both the switch and the PHYs.
105
XTAL_OUT

MDC
Input
MDC is the management data clock reference for the serial
management interface (SMI). A continuous clock stream is
not expected. The maximum frequency supported is 8.3 MHz.
The SMI is used to access the registers in the PHY and in the
Switch if the serial EEPROM is not accessing the registers. It
is available in all combinations of SW_MODE[1:0].
MDC is internally pulled high via a resistor.
71
MDIO
I/O
MDIO is the management data Input/Output for the SMI.
MDIO is used to transfer management data in and out of the
device synchronously with MDC. This pin requires an external
pull-up resistor in the range of 4.7 kΩ to 10 kΩ.
The 88E6060 device uses 16 of the 32 possible SMI port
addresses. The 16 that are used are selectable using the
EE_CLK/ADDR4 pin.
MDIO is internally pulled high via a resistor.
63
INTn
Open Drain
Output
INTn is an active low, open drain pin that is asserted to indicate an unmasked interrupt event occurred. A single external
pull-up resistor is required to achieve a logic high when this
signal is inactive.
The INTn pin is asserted active low if SW_MODE[1:0] (see
Table 14) bits are not 0b10 (standalone mode) and the
EEPROM data has been completely read into the device. This
EEPROM done interrupt indicates to any attached CPU that it
may use the MDC/MDIO lines to access the internal registers
because the EEPROM has finished using the registers. This
pin also goes low when any other unmasked interrupt
becomes active inside the device.

EE_CS
/EE_1K
I/O
Serial EEPROM chip select. EE_CS is the serial EEPROM
chip select referenced to EE_CLK. It is used to enable the
external EEPROM (if present), and to delineate each data
transfer.
Input during
reset
EE_CS is a multi-function pin used to configure the 88E6060
during a hardware reset. When reset is asserted, EE_CS
becomes an input and the desired EEPROM type configuration is latched at the rising edge of RESETn as follows:
Low = Use 8-bit addresses (for 2K bit 93C56 & 4K bit
93C66)
High = Use 6-bit addresses (for 1K bit 93C46)
The external EEPROM must be configured in the x16 organization.
EE_CS is internally pulled high via a resistor. Use a 4.7 kΩ
resistor to VSS for a configuration low.

Loading
Serial EEPROM clock. EE_CLK is the serial EEPROM clock
reference output by the 88E6060. It is used to shift the external serial EEPROM (if installed) to the next data bit so the
default values of the internal registers can be overridden.
EE_CLK is a multi-function pin used to configure the
88E6060 during a hardware reset. When reset is asserted,
EE_CLK becomes an input and the desired SMI ADDR4
address space configuration (Table 5) is latched at the rising
edge of RESETn as follows:
Low = Use SMI device addresses 0x00 to 0x0F
High = Use SMI device addresses 0x10 to 0x1F
EE_CLK is internally pulled high via a resistor. Use a 4.7 kΩ
resistor to VSS for a configuration low.

P5_INCLK
I/O
Input Clock. P5_INCLK is a reference for P5_INDV and
P5_IND[3:0]. The direction and speed of P5_INCLK is determined by P5_MODE[3:0] at the end of reset.
If the port is in PHY Mode, P5_INCLK is an output. In this
mode the frequency of the clock is 25 MHz if the port is in
100BASE-X mode, 2.5 MHz if the port is in 10BASE-T mode
and 50 MHz for RMII mode.
If the port is in MAC Mode, P5_INCLK is an input. In this
mode the frequency of the clock can be anywhere from DC to
25 MHz although it should be 25 MHz for 100BASE-X mode
and 2.5 MHz for 10BASE-T mode.
P5_INCLK is tri-stated during reset and it is internally pulled

inputs regardless of the port’s mode (i.e., PHY mode or MAC
mode). Only P5_IND0 is used when SNI mode is selected.
P5_IND[1:0] are used when RMII mode is selected1.
P5_IND[3:0] are internally pulled high via resistor.
87
P5_INDV

Input Data Valid. When P5_INDV is asserted high, data on
P5_IND[3:0] is accepted into the switch. P5_INDV must be
synchronous to P5_INCLK for SNI and MII operation. It must
be synchronous to P5_OUTCLK or P5_INCLK in RMII operation.
P5_INDV is internally pulled low via resistor.
1. When RMII mode is selected P5_IND[1:0] are synchronous to P5_OUTCLK or P5_INCLK which are phase shifted to each other.

Description
CPU attached mode – ports come up disabled1
Reserved
Stand alone mode - ignore EEPROM
EEPROM attached mode2
The EEPROM attached mode (when both SW_MODE pins =
high) can be used with a CPU. In all but the standalone
modes, the INTn pin asserts active low after the EEPROM
completes initializing the internal registers (i.e. a halt command has been executed)3.
SW_MODE[1:0] are not latched on the rising edge of Reset
and they must remain static for proper device operation. They
are internally pulled high via resistors.
64
FD_FLOW_DIS
Input
Full-duplex Flow Control disable.
High = disable flow control on all full-duplex ports
Low = enable IEEE 802.3x Pause based flow control on all
supported full-duplex ports
Full-duplex flow control requires support from the end station.
Full-duplex flow control is supported on any full-duplex port
that has Auto-Negotiation enabled, advertises that it supports
Pause (i.e., FD_FLOW_DIS = Low at reset), and sees that
the end station supports Pause as well (from data returned
during Auto-Negotiation). If any of these requirements are not
met the port does not generate Pause frames and it does not
pause when the port receives Pause frames.
FD_FLOW_DIS is latched on the rising edge of Reset into all
the port’s PHY Auto-Negotiation Advertisement registers. It is
internally pulled high via a resistor.
The EE_DIN/HD_FLOW_DIS multi-function pin is used to
select Flow control on half-duplex ports (see Table 7)
1. The ports come up in the Disabled Port State in the CPU mode so the CPU can perform bridge loop detection on link up and/or perform switch initialization/configuration prior to letting packets flow.
2. In EEPROM attached mode the ports come up in the Forwarding Port State unless the Port Control register is overwritten by the
EEPROM data.
3. The INTn pin is activated so the CPU can access the registers using the MDC/MDIO pins. The CPU cannot access these registers as
long as the EEPROM is still being executed.

Link Street® 88E6060 - Unrestricted
Low Power, 6-port, 10/100 Ethernet Switch
Section 2. Application Examples
The Marvell® 88E6060 device supports many different applications with few additional active components in a
small footprint. The 88E6060 contains six ports with five PHYs. This architecture allows all five PHYs to be active
and available while at the same time supporting one independent MII interface.
The higher integration, low power, and an extra port saves BOM costs on designs requiring six ports or two MII
interfaces. The flexibility of the 88E6060 device comes from its configuration options on Port 0 and Port 1, and its
configuration options on its two MII ports (Port 5’s MII interface is always on, while Port 4 can be an MII or a PHY).
The device also supports an optional EEPROM (93C46 type) to override any of the default settings.
The only active components required to implement a complete 88E6060 10/100 Ethernet switch are:
•
•
•
25 MHz crystal clock source or a 25 or 50 MHz oscillator
Low-cost PNP transistor used to regulate 2.5V down from 3.3V
Low-cost PNP transistor used to regulate 1.5V down from 3.3V
The 88E6060 is a full system on a chip containing the PHYs, LED drivers, voltage regulator logic, switch logic, and
memory. In addition, it is pin compatible with the Marvell® 88E6063 QoS switch.
2.1 Examples with the 88E6060
The 88E6060 has multiple configuration options selectable through four pins: P[1:0]_CONFIG, ENABLE_MII5, and
DISABLE_MII4. Table 1 shows Port 0 and Port 1 Copper or Fiber configuration settings, and Port 5 and Port 4
configuration settings. Ports 2, 3, and 4’s default configuration is Auto-Negotiation enabled.

Application Examples
Examples with the 88E6060
Each of the following modes are described in detail below:
•
•
•
Firewall Router Switch w/four 10/100BASE-T LAN ports & one 10/100BASE-T WAN port
Firewall Router Switch supporting a Fiber WAN port (using port 0 or port 1)
Firewall Router Switch with four 10/100BASE-T LAN ports & an MII port for a WAN PHY (using port 4)
For the firewall router examples, Port 5 is configured in PHY Mode, and Ports 0 to 4 support 100BASE-TX and/or
10BASE-T operation. Port 0 could be 100BASE-FX if desired as a fiber interface from the WAN (see Figure 3).
The CPU’s SMI is used to access all the PHY and Switch registers inside the 88E6060.
In Figure 2, Port 0 is used as a WAN interface in the LAN. To make this work, the WAN port needs to be isolated
from the LAN ports, and vice versa. LAN frames cannot go directly to the WAN, and WAN frames cannot go
directly to the LAN. The CPU’s port needs to be the bridge by transmitting, receiving, and translating frames from
both the WAN and to and from the LAN. The 88E6060 supports port based VLANs in any programmable configuration that support this requirement and a Marvell header mode supports dynamic VLANs on the CPU’s port.
Bringing the 802.3 WAN PHY into the 88E6060’s Port 0 not only reduces BOM costs, but it also adds the feature
of a 10/100 Mbps interface with Auto Crossover cable support (supported on all copper ports).

Functional Description
Switch Data Flow
Section 3. Functional Description
This section describes the wire-speed, non-blocking 6-port 10/100-Mbps Fast Ethernet switch core that is integrated into the 88E6060 device. The six ports include PHY, RMII/MII/SNI, and internal MII ports, as described
below.
3.1 Switch Data Flow
The 88E6060 device accepts IEEE 802.3 frames and either discards them or transmits them out of one or more of
the switchports. The decision on what to do with each frame is one of the many jobs handled inside the switch.
Figure 5 shows the data path inside the switch along with the major functional blocks that process the frame as it
travels through the 88E6060 device.

The PHY, or physical layer interface, is used to receive and transmit frames over CAT 5 twisted pair cable or fiberoptic cables (only Port 0 and Port 1 support a fiber option). The 88E6060 device contains five PHYs connected to
Port 0 to Port 4. The PHY block is covered in detail in Section 4.
Port 5 does not contain PHYs. Instead, a short distance industry standard digital interface is supported and generically called the port’s Media Independent Interface (MII see “MII/SNI/RMII” on page 41). Many interface modes
and timings are supported so that a large number of external device types can be used.
The two MIIs (Port 4 can be MII or PHY) on the 88E6060 support four major modes of operation and each Media
Independent Interface (MII) can be configured independently.
The 88E6060 contains six independent MACs (Section 3.3) that perform all of the functions in the 802.3 protocol:

•
•
Frame formatting
CRC checking
CSMA/CD enforcement

The switch portion of the 88E6060 receives good packets from the MACs, processes them, and forwards them to
the appropriate MACs for transmission. Processing frames is the key activity, and it involves the Ingress Policy,
the Queue Controller, the Output Queues, and the Egress Policy blocks shown in Figure 6. The Egress Policy
block is only applicable to the MII ports (Port 4 and Port 5). These blocks modify the normal or default packet flow
through the switch and are discussed in section 3.5 to section 3.7.

MII/SNI/RMII
3.2 MII/SNI/RMII
The Media Independent Interface (MII) supports four major modes of operation:
•
•
•
•
MII PHY Mode (The 88E6060 device drives the interface clocks - see Section 3.2.1 for details.)
MII MAC Mode (The external device drives the interface clocks - see Section 3.2.2 for details.)
SNI PHY Mode
RMII PHY Mode
The two MII ports can be configured differently from each other.
3.2.1
MII PHY Mode
The MII PHY Mode (Reverse MII) configures the selected MAC inside the 88E6060 device to emulate a PHY. This
enables the 88E6060 device to be directly connected to an external MAC (for example, one inside a Router CPU).
In this mode, the 88E6060 device drives the interface clocks (Px_INCLK and Px_OUTCLK); therefore, the
required frequency needs to be selected. Both full-duplex and half-duplex modes are supported and need to be
selected to match the mode of the link partner’s MAC. The MII PHY interface is compliant with the IEEE 802.3u
clause 22.

MII MAC Mode
The MII MAC Mode (Forward MII) configures the desired MAC inside the 88E6060 device to act as a MAC so that
it can be directly connected to an external PHY. In this mode, the 88E6060 device receives the interface clocks
(Px_INCLK and Px_OUTCLK) and works at any frequency from DC to 25 MHz. The two clocks can be asynchronous with respect to each other. Both full-duplex and half-duplex modes are supported and need to be selected to
match the mode of the link partner’s MAC. The MII MAC interface is compliant to the IEEE 802.3u clause 22.

SNI PHY Mode
The SNI PHY Mode (7-Wire interface) configures the selected MAC inside the 88E6060 device to act as a
10 Mbps PHY, enabling it to be directly connected to an external 10 Mbps-only MAC (such as one inside a Router
CPU). In this mode, only one data bit is used on each of input and output (Px_IND0 and Px_OUTD0). The interface clocks, Px_INCLK and Px_OUTCLK, are driven by the 88E6060 device. Since SNI was never standardized,
the 88E6060 device supports various SNI modes. The active edge of the clock (either rising or falling) and the
active level on the collision signal (either active high or low) can be selected.
In SNI mode, the output data from the switch is indicated to be valid by the CRS signal. CRS is not synchronous
with OUT_CLK, however. So the receiving MAC needs to detect the beginning of the frame by looking for the Preamble and then the Start of Frame Delimiter (SFD). CRS will be deasserted asynchronously at the end of the
frame so the receiving MAC needs to tolerate the presence of these extra 'dribble' bits

Low Power, 6-port, 10/100 Ethernet Switch
3.3 Media Access Controllers (MAC)
The 88E6060 device contains six independent MACs that perform all of the functions in the 802.3 protocol that
include, among others, frame formatting, frame stripping, FCS checking, CSMA/CD enforcement, and collision
handling.
Each MAC receive block checks incoming packets and discards packets with CRC errors, alignment errors, short
packets (less than 64 bytes), or long packets (more than 1522 bytes)1. Each MAC constantly monitors its receive
lines waiting for preamble bytes followed by the Start of Frame Delimiter (SFD). The first six bytes after the SFD
are used as the packet’s Destination Address (DA), and the next six bytes are used as the packet’s Source
Address (SA). These two addresses are fundamental to the operation of the switch (see section 3.4). The last four
bytes of the packet contain the packet’s Frame Check Sequence (FCS). The packet is discarded if the FCS does
not meet the IEEE 802.3 CRC-32 requirements.
Before a packet can be sent out, the transmit block must check whether the line is available for transmission. The
transmit line is available all the time when the port is in full-duplex mode, but the line could be busy receiving a
packet when the port is in half-duplex mode. In this case, the transmitter defers its transmission until the line
becomes available, when it ensures that a minimum interpacket gap of at least 96 bits occurs before transmitting
a 56-bit preamble and an 8-bit Start of Frame Delimiter (SFD) ahead of the basic frame. Transmission of the frame
begins immediately after the SFD.
For the half-duplex mode, the 88E6060 device also monitors the collision signal while it is transmitting. When a
collision is detected (i.e., both transmitter and receiver of a half-duplex MAC are active at the same time), the MAC
transmits a JAM pattern and then delays the retransmission for a random time period determined by the IEEE
802.3 backoff algorithm. In full-duplex mode, the collision signal and backoff algorithm are ignored.
3.3.1
Backoff
In half-duplex mode, the 88E6060 device’s MACs implement the truncated binary exponential backoff algorithm
defined in the IEEE 802.3 standard. This algorithm starts with a randomly-selected small backoff time and follows
by generating progressively longer random backoff times. The random times prevent two or more MACs from
always attempting re-transmission at the same time. The progressively longer backoff times give a wider random
range at the expense of a longer delay, giving congested links a better chance of finding a winning transmitter.
Each MAC in the 88E6060 device resets the progressively longer backoff time circuit after 16 consecutive
retransmit trials. Each MAC then restarts the backoff algorithm with the shortest random backoff time and
continues to retry and retransmit the frame. A packet that successively collides with a retransmit signal is retransmitted until transmission is successful. This algorithm prevents packet loss in highly-congested
environments. The MACs in the switch can be configured to meet the IEEE 802.3 specification and discard a
frame after 16 consecutive collisions instead of restarting the backoff algorithm. To discard a frame after 16
consecutive collisions, set the DiscardExcessive bit to a one in the Global Control register—see Table 53.
3.3.2
Half-Duplex Flow Control
Half-duplex flow control is used to throttle the end station to avoid dropping packets during network congestion. It
is enabled on all half-duplex ports when the EE_DIN/HD_FLOW_DIS pin is low at the rising edge of RESETn. The
88E6060 device uses a collision-based scheme to perform half-duplex flow control. When the free buffer space is
almost exhausted, the MAC forces a collision in the input port when the 88E6060 device senses an incoming
packet. Only those ports that are involved in the congestion are flow controlled. When the half-duplex flow control
mode is not set and no packet buffer space is available, the incoming packet is discarded.
1. A maximum frame size of 1536 bytes is supported by setting the MaxFrameSize bit in the Global Control register
(section 6.2.3).

3.3.3
Full-Duplex Flow Control
The purpose of full-duplex flow control is the same as that of flow control in the half-duplex case—to avoid dropping packets during congestion. Full-duplex flow control is enabled on all full-duplex ports when:
•
•
•
FD_FLOW_DIS pin is low at the rising edge of RESETn, and
Auto-Negotiation is enabled on the port (see section 4.2.13), and
The link partner ‘advertises’ that it supports pause during Auto-Negotiation1
Full-duplex flow control is not automatically supported on Ports 0–1 when configured for 100BASE-FX operation,
nor for Port 5 and Port 4 when it is in MII mode. This is because Auto-Negotiation is not defined for 100BASE-FX
or MII. Therefore, the link partners cannot advertise that they support Pause. It can be forced, however—see section 3.3.4. When the full-duplex flow control mode is not set and no packet buffer space is available, the incoming
packet is discarded.
In full-duplex mode, the 88E6060 MACs support the standard flow control defined in the IEEE 802.3x specification. This flow control enables stopping and restoring the transmission from the remote node. The basic mechanism for performing full-duplex flow control is by means of a Pause frame. The format of the Pause frame is shown
in Table 20.

Full-duplex flow control functions as follows. When the free buffer space is almost exhausted, the 88E6060 device
sends out a Pause frame with the maximum Pause time (a value of all ones—0xFFFF) to stop the remote node
from sending more frames into the switch. Only the node that is involved in the congestion is Paused. When the
event that invoked flow control disappears, the 88E6060 device sends out a Pause frame with the Pause time
equal to zero, indicating that the remote node can resume transmission. The 88E6060 device also responds to the
Pause command in the MAC receiving block. When the Pause command is detected, the MAC responds within
one slot time (512 bit times) to stop transmission of the new data frame for the amount of time defined in the pause
time field of the Pause command packet.
The Source Address of received Pause frames is not learned (see Address Learning in section 3.4.3) since it may
not represent the Source Address of the transmitting port. This is generally the case if the link partner is an
unmanaged switch. The 88E6060 device can be configured to transmit a unique Source Address on Pause
frames (the default is all zeros). Global Switch MAC Address registers 1, 2, and 3 (see Table 50, Table 51, and
Table 52) can be set to the Source Address to use. A single fixed Source Address can be used for all ports, or a
unique Source Address per port can be selected by changing the value of the DiffAddr bit in Table 50.
The MACs always discard all IEEE 802.3x Pause frames that they receive, even when full-duplex flow control is
disabled or even when the port is in half-duplex mode.
1. Full-duplex flow control is not automatically supported on ports configured for 100BASE-FX operation since Auto-Negotiation is not
defined for 100BASE-FX, and hence, the link partners cannot advertise that they support Pause. It can be forced, however – see
section 3.3.4.

Forcing Flow Control
When flow control is enabled using the 88E6060 device’s pins, it is enabled for all ports of the same type (i.e., on
all half-duplex ports or on all full-duplex ports that have a flow-controllable link partner). It may be required to have
flow control enabled on only one or two ports and have all the other ports disabled. In this case, flow control
should be disabled using the appropriate device pins. Refer to the FD_FLOW_DIS and HD_FLOW_DIS pin
descriptions for disabling flow control then use the port’s ForceFlowControl bit in the Port Control Register for
enabling flow control on individual ports. (see section 6.2.2).
3.3.5
Statistics Counters
Sometimes it is necessary to debug network occurrences. For example, a technician may want to view the network remotely to solve a customer problem or a software programmer may want to trace transmitted frames. In
these situations, two basic types of data are important:
•
•
Number of good frames entering and leaving each port of the switch
Quality of network segment performance
Frame size and the distribution of frames between multicast and unicast types are less important in this kind of
debugging for an edge switch.
The 88E6060 Statistics Counters support basic debugging needs. Each port can capture two kinds of statistics:
•
•
A count of the number of good frames received with the number of frames transmitted, or
A count of the number of bad frames received with the number of collisions encountered
The first statistic answers the question “Where did all the frames go?”, while the second statistic answers the
question “Does the network segment have any performance problems?”. These counters are described in
Table 47, and in Table 48. The counters can be cleared, and their mode chosen by the CtrMode bit in the Switch
Global Control register (section 6.2.3).

Address Management
3.4 Address Management
The primary function of the switch portion of the 88E6060 device is to receive good packets from the MACs, processes them, and forward them to the appropriate MACs for transmission. This frame processing involves the
Ingress Policy, Queue Controller, Output Queues, and Egress Policy blocks shown in Figure 6. These blocks modify the normal or default packet flow through the switch and are discussed following section 3.5. The normal
packet flow and processing is discussed first.
The normal packet flow involves learning how to switch packets only to the correct MACs. The switch learns which
port an end station is connected to by remembering each packet’s Source Address along with the port number on
which the packet arrived.
When a packet is directed to a new, currently unlearned MAC address, the packet is transmitted out of all of the
ports1 except for the one on which it arrived2. Once a MAC address/port number mapping is learned, all future
packets directed to that end station’s MAC address (as defined in a frame’s Destination Address field) are directed
to the learned port number only. This ensures that the packet is received by the correct end station (if it exists),
and when the end station responds, its address is learned by the switch for the next series of packets.
Owing to the limitation of physical memory, switches learn only the currently “active” MAC addresses—a small
subset of the 248 possible MAC addresses. When an end station is moved from one port to another, a new MAC
address/port number association must be learned, and the old one replaced. These issues are handled by the
‘Aging’ and ‘Station Move Handling’ functions. A MAC address/port number association is allowed to be “active”
for only a limited time. This time limit is typically set to five minutes.
3.4.1
Address Translation Unit
The 88E6060 device’s Lookup Engine or Address Translation Unit (ATU) gets the DA and SA from each frame
received from each port. It performs all address searching, address learning, and address aging functions for all
ports at wire speed rates. For example, a DA and an SA lookup/learn function can be performed for all ports in
less time than it takes to receive a 64-byte frame on all ports.
The address database uses a hashing technique for quick storage and retrieval. Hashing a 48-bit address into
fewer bits results in some MAC addresses having the same hash address. This situation is called a hash collision
and is solved in the 88E6060 device by using a four entry bin per hash location that can store up to four different
MAC addresses at each hash location. The four-entry bin is twice as deep as that of many competing switching
devices and allows for a reduced size of the address database while still holding the same number of active random value MAC addresses.
The address database is stored in the embedded SRAM and has a default size of 1024 entries with a default
aging time of about 300 seconds or 5 minutes. The size of the address database can be modified to a maximum of
256, 512, or 1024 entries. Decreasing the size of the address database increases the number of buffers available
for frames (see Figure 11). The age time can be modified in 16 second increments from 0 seconds (aging disabled) to 4080 seconds (or 68 minutes). These options are set in the ATU Control register (Table 54).
Note
Changing the ATU size will result in ATU reset and SWReset. SWReset will reset the MAC, and the Port
State bits will be set back to their configuration reset value. The ATU Reset will reset the entire ATU
database. See ATUSize and SWReset register descriptions in Table 54.
1. Port-based VLANs modify this operation (section 3.5.1).
2. The 88E6060 device can be configured to transmit frames out the same port that they came in on—see Table 45.

Address Searching or Translation
The address search engine searches the address database to get the output port number(s), called the Destination Port Vector (DPV), for each frame’s Destination Address (DA). When an address is found, it can switch the
frame instead of flooding it. If the destination address is not found, then the packet is flooded. Flooding refers to
the action of sending frames out to all the ports of the switch that have link up with PortState not "Disabled",
except for the port the frame came in on. The switch arbitrates destination address lookup requests from the ports
and grants one lookup at a time. The MAC address is hashed, and then data is read from the SRAM table and
compared to the MAC address for a match. Four different addresses can be stored at each hash location. When a
match is found, the Address Translation Unit (ATU) returns the DPV to the Ingress Policy block where it may get
modified before the packet is queued to the output port(s). The DPV returned from the ATU may get modified by
the VLANTable data. When no MAC address match is found, the Ingress Policy block uses a unique default DPV
for each Ingress port, which typically floods the frame. The default DPV for each port is the Port’s VLANTable data
– see Table 45. When the destination address in the frame is a multicast address or broadcast address, the
address is searched in the same way as a unicast address, and the frame is processed identically. Multicast
addresses cannot be learned, so they appear in the address database only when they are loaded into it by a CPU
or the EEPROM – see section 3.4.5.3. This feature is used for multicast filtering and Bridge Protocol Data Unit
(BPDU) handling. BPDU frames are special frames used for Spanning Tree or bridge loop detection.
Multiple separate address databases are supported in the 88E6060 device. The database that is searched is controlled by the port’s default database number (DBNum - Table 45). MAC addresses that are not members of the
port’s DBNum cannot be found.

3.4.3
Address Learning
The address learning engine learns source addresses of incoming frames. Up to 1024 MAC address/port number
mappings can be stored in the address database. See section 3.4.1. When the source address from an input
frame cannot be found in the address database, the ATU enters the self-learning mode, places the new MAC
address/port number mapping into the database, and refreshes its Age time. The Age time on a MAC Address
entry is refreshed by setting its Entry_State field to 0xE. When the MAC address is already in the database, the
port number1 and Age associated with the entry is updated and/or refreshed. The port number is updated in case
the end station has moved, and the port number needs to be corrected. The entry’s Age is refreshed since the
MAC address is still “active”. This refreshing prevents the MAC address/port number mapping from being prematurely removed as being “inactive”.
When an address is added into the database it is hashed and then stored in the 1st empty bin found at the hashed
location. When all four address bins are full, a “least recently used” algorithm is used to scan each entry’s Age
time in the Entry_State field. The Entry_State field is described in section 3.4.5.1. When all four address bins have
the same Age time, then the 1st unlocked bin is used (see section 3.4.5.1 for more information about locked or
static addresses). If all four bins are locked then the address is not learned and an ATUFull interrupt is generated.
See the Switch Global Status register – Table 49.
Multiple separate address databases are supported in the 88E6060 device. The port’s database number (DBNum
- Table 45) determines the MAC address database into which the learned address is stored. The same MAC
address can be learned multiple times with different port mappings if different DBNum values are used.
Learning can be disabled for all ports by setting the LearnDis bit to a one in the ATU Control register (Table 54).
Learning is disabled on any port that has a PortState of Disabled or Blocking/Listening (see the Port Control register—Table 44) or whose Port Association Vector (PAV bit — Table 46) is cleared to a zero.
3.4.4
Address Aging
Address aging makes room for new active addresses by ensuring that when a node is disconnected from the network segment or when it becomes inactive, its entry is removed from the address database. An address is
removed from the database after a predetermined interval from the time it last appeared as an Ingress frame’s
source address (SA). This interval is programmable in the 88E6060 device. The default Aging interval is about 5
minutes (282 to 304 seconds), but it can be set from 0 seconds (i.e., aging is disabled) to 4,080 seconds in 16
second increments. See AgeTime in ATU Control register—see Table 54.
The 88E6060 device runs the address aging process continuously unless disabled by clearing the AgeTime field
in the ATU Control register to zero. Aging is accomplished by a periodic sweeping of the address database. The
speed of these sweeps is determined by the AgeTime field. On each aging sweep of the database, the ATU reads
each valid entry and updates its Age time by decrementing its Entry_State field as long as the entry is not locked.
The Entry_State field is described in section 3.4.5.1. When the Entry_State field reaches zero, the entry is considered invalid and purged from the database.
The time taken to age out any entry in the MAC address database is a function of the AgeTime value in the ATU
Control register and the value in the Entry_State field. A new or just-refreshed unicast MAC address has an
Entry_State value of 0xE. See section 3.4.2. A purged or invalid entry has an Entry_State value of 0x0. The values
from 0xD to 0x1 indicate the Age time on a valid unicast MAC address with 0x1 being the oldest. This scheme provides 14 possible age values in the Entry_State field which increases precision in the age of entries in the MAC
address database. This precision is relayed to the “least recently used” algorithm that is employed by the address
1. The port’s Port Association Vector (PAV - Table 46) is used as the port’s port vector when an address is auto learned or updated.

Address Translation Unit Operations
The ATU in the 88E6060 device supports user commands to access and modify the contents of the MAC address
database.
All ATU operations have the same user interface and protocol. Five Global registers are used and are shown in
Table 21 on page 52. The protocol for an ATU operation is as follows:
1.

Ensuring the ATU is available by checking the ATUBusy bit in the ATU Operation register. The ATU can only
perform one user command at a time.
Loading the ATU Data and ATU MAC registers, if required by the operation.
Starting the ATU operation by defining the DBNum, ATUOp, and setting the ATUBusy bit to a one in the ATU
Operation register. The DBNum, ATUOp and the ATUBusy bits setting can be done at the same time.
Waiting for the ATU operation to complete. Completion can be verified by polling the ATUBusy bit in the ATU
Operation register or by receiving an ATUDone interrupt. See Switch Global Control register Table 53 and

The Entry_State field, together with the entry’s Multicast bit (bit 40) is used to determine the entry’s age or its type as follows:
For unicast MAC addresses (bit 40 = 0):
0x0 = Invalid, empty, or purged entry.
0x1 to 0xE = Valid entry where the Entry_State = the entry’s age, and the DPV
indicates the port or ports mapped to this MAC address.
0xF = Valid entry that is locked and does not age. The DPV indicates the port or
ports mapped to this MAC address.
For multicast MAC addresses (bit 40 = 1):
0x0 = Invalid, empty, or purged entry.
0x7 = Valid entry that is locked does not age. The DPV indicates the port or ports
mapped to this MAC address. Used for multicast filtering.
0xE = Valid entry that is locked and does not age. The DPV indicates the port or
ports mapped to this MAC address. Frames with a MAC address that return this
Entry_State are considered MGMT (management) frames and are allowed to tunnel through blocked ports (see section 3.5). Used for BPDU handling.
DPV

The Destination Port Vector. These bits indicate which port or ports are associated
with this MAC address (i.e., where frames should be switch to) when they are set to a

assigned to physical Port 0, 53 to Port 1, 54 to Port 2, 55 to Port 3, and so on.

Reading the Address Database - the Get Next Operation
The contents of the address database can be dumped or searched. The Get Next operation returns the active
contents of the address database in ascending network byte order. A search operation can also be done using the
Get Next operation. If multiple address databases are being used, the Get Next function returns all unique MAC
addresses from the selected database.
The Get Next operation starts with the MAC address contained in the ATU MAC registers and returns the next
higher active MAC address currently active in the address database. Use an ATU MAC address of all ones to get
the first or lowest active MAC address. The returned MAC address and its data is accessible in the ATU MAC and
the ATU Data registers. To get the next higher active MAC address, the Get Next operation can be started again
without setting the ATU MAC registers since they already contain the ‘last’ address. A returned ATU MAC address
of all ones indicates that the end of the database has been reached1. A summary of how the Get Next operation
uses the ATU’s registers is shown in Table 23.

3.4.5.3
Loading and Purging an Entry in the Address Database
Any MAC address (unicast or multicast) can be loaded into, or removed from, the address database by using the
Load operation. An address is loaded into the database if the Entry_State in the ATU Data register (Table 56) is
non-zero. A value of zero indicates the required ATU operation is a purge.

The load operation searches the address database indicated by the database number, DBNum (in the ATU Operation register), for the MAC address contained in the ATU MAC registers. When the address is found, it is updated
by the information found in the ATU Data register.
Note
A load operation becomes a purge operation when the ATU Data’s Entry_State equals zero. Also, locked
addresses can be modified without their needing to be purged first.
If the address is not found and if the ATU Data’s Entry_State does not equal zero, the address is loaded into the

Port-based VLANs
The 88E6060 device supports a very flexible port-based VLAN feature.
Each Ingress port is associated with the VLANTable field of the Port-based VLAN Map register that restricts which
egress ports its frames may use. (Table 45 on page 96). When bit 0 of a port’s VLANTable field is set to a one, that
port is allowed to send frames to Port 0. When bit 1 of this field is set to a one, that port is allowed to send frames
to Port 1. If bit 2 equals 1, Port 2 may receive frames, If bit 3 equals 1, Port 3 may receive frames, and so on. At
reset the VLANTable value for each port is set to all ones, except for each port’s own bit, which is cleared to a
zero. This prevents frames from going back out of the port at which they arrived. This default VLAN configuration
allows all of the ports to send frames to all of the other ports as shown in Figure 13.

One reason for VLAN support in the 88E6060 device is to isolate a port for firewall router applications. Figure 14
shows a typical VLAN configuration for a firewall router. Port 0 is the WAN port. The frames arriving at this port
must not go out to any of the LAN ports, but they must be able to go to the router CPU. All the LAN ports are able
to send frames directly to each other without the need for CPU intervention but they cannot send frames directly to
the WAN port. To accomplish routing, the CPU is able to send frames to all of the ports. The use of the Marvell
header (section 3.5.4) enables a CPU to define dynamically to which port or ports a frame is allowed to go. This
feature is useful for purposes of WAN and LAN isolation on multicast or flooded traffic generated by the CPU.

Tunneling Frames Through Port-Based VLANS
Normally frames cannot pass through the port based VLAN barriers. However, some frames can be made to pass
through the VLAN barriers on the 88E6060 device. Before a frame can tunnel through a port based VLAN barrier,
its destination address (DA) must be locked into the address database (section 3.4.5.1), and the VLANTunnel bit
on the frame’s Ingress port must be set to a one (Table 44 on page 94). When both of these conditions are met,
the frame is sent out of the port or ports indicated in the locked address’s DPV field for the DA entry in the address
database. The VLANTable data is ignored in this case. This feature is enabled only on those ports that have their
VLANTunnel bit set to a one.

Switching Frames Back to their Source Port
The 88E6060 device supports the ability to return frames to the port at which they arrived. While this is not a standard way to handle Ethernet frames, some applications may require this ability on some ports. This feature can be
enabled on a port-by-port basis by setting the port’s own bit in its VLANTable register to a one. See section 3.5.1
and Table 45.
3.5.3
Port States
The 88E6060 device supports four Port States per port as shown in Table 26. The Port States are used by the
Queue Controller (section 3.6) in the 88E6060 device to adjust buffer allocation. They are used by the Ingress Policy blocks to control which frame types are allowed to enter and leave the switch, so that Spanning Tree or other
bridge loop detection software can be supported. The PortState bits in the Port Control register (Table 44) determine each port’s Port State, and they can be modified at any time.
Table 26 below lists the Port States and their function. Two of the Port States require the detection of MGMT
frames. A MGMT frame in the 88E6060 device is any multicast frame whose DA address is locked into the
address database with an Entry_State value of 0xE (section 3.4.5.1). MGMT frames can tunnel through blocked
ports. MGMT frames always ignore VLANs (i.e., they always go to the port indicated by the DA’s DPV). These
MGMT frames are typically used for 802.1D Spanning Tree Bridge Protocol Data Units (BPDUs), but any multicast
address can be used supporting new and/or proprietary protocols.
Table 26:
Port State Options
Port Sta t e
Desc ription
Disabled
Frames are not allowed to enter (ingress) or leave (egress) a disabled port. Learning does not
take place on disabled ports.
Blocking/
Listening
Only MGMT frames are allowed to enter or leave a blocked port. All other frame types are discarded. Learning is disabled on blocked ports.
Learning
Only MGMT frames are allowed to enter or leave a learning port. All other frame types are discarded, but learning takes place on all good frames even if they are not MGMT frames.
Forwarding
Normal operation. All frames are allowed to enter and leave a forwarding port. Learning takes
place on all good frames.
The default Port State for all the ports in the switch can be either Disabled or Forwarding depending upon the
value of the SW_MODE pins (see Pin Description in Part 1 of this datasheet). The ports come up in the Forwarding Port State unless the SW_MODE is for CPU-attached mode. This enables the CPU to bring up the ports slowly
after port-based VLANs are configured (for router WAN to LAN isolation) and so a Spanning tree protocol can be
run (if required).

3.5.5
Switch’s Ingress Trailer (Port 4 and Port 5 only)
When a CPU needs to perform Spanning Tree or bridge loop detection or when it needs to be able to send frames
out any port or ports, then the CPU’s port needs to be configured for Ingress Trailer mode. Any MII port (Port 4 and
Port 5) can be configured this way by setting the IngressMode bits in the port’s Port Control register (Table 44 on
page 94), but only the CPU’s port should be configured this way.
When the Ingress Trailer mode is enabled on a port, the last four bytes of the data portion of the frame are used to
configure the switch—see Figure 15. The Ingress Policy block removes the Trailer from the frame and overwrites
it with a new CRC, causing the frame to be four bytes smaller in size. This adjustment makes the frame ‘normal’
for the rest of the network since the Trailer’s data is intended for the switch only. Frame size checking is performed
on the adjusted frame size. This means the CPU must always add four bytes of data to the end of every frame it
sends into the switch when the Trailer mode is enabled.
The Ingress Trailer gives the CPU the ability to override normal switch operation on the frame that it just transmitted but this override may not always be necessary. When the CPU requires the switch to process the frame with
the switch’s current ingress policy, the CPU sets the Trailer data in the frame to all zeros by inserting a four-byte
pad. This zero padding clears the Override bit in the Trailer causing the switch to ignore the Trailer’s data and process the frame normally after removing the Trailer from the frame.
When the CPU needs to override all of the switch’s Ingress policy including Port Based VLANs, it sets the fields in
the Trailer as shown in Figure 15 and defined in Table 27.
The ingress trailer is used to force a frame to egress out certain ports and it is the only way for the CPU to tunnel
a frame through blocked ports.(by using the MGMT bit). When the CPU uses the trailer it must "know" where it
wants the frame to go.

Override
When this bit is set to a one, the Trailer data is used to override the switch’s operation. When this
bit is cleared to a zero, the Trailer’s DPV and MGMT bits are ignored.
LearnDisable
When this bit is set to a one (with or without the Override bit being set) the Source Address contained in this frame will not be learned in the address database.
IgnoreFCS
When this bit is set to a one (with or without the Override bit being set) the frame’s FCS is
ignored (i.e., the FCS is not checked to see if the frame should be discarded due to a CRC error).
The FCS is still a required part of the frame, however, its value is not verified if this bit is set in the
Trailer. A new, correct CRC is written to the last four bytes of the frame and the frame is processed by the switch with the good CRC.
DPV[5:0]
The Destination Port Vector. These bits indicate which port or ports the frame is to be sent to if
the Override bit is set to a one. A DPV of all zeros discards the frame. Bit 0 is assigned to physical Port 0 and must be set to a one for this frame to egress from that port, bit 1 for Port 1, bit 2 for
Port 2, bit 3 for Port 3, and so on.
MGMT
The frame’s management bit. When this bit is set to a one (along with the Override bit) indicates
the frame is a MGMT frame and is allowed to Ingress and Egress through Blocked ports (section
3.5.3). Must be set on BPDU frames.

3.6 Queue Controller
The 88E6060 queue controller uses an advanced non-blocking, output port queue architecture with Resource
Reservation. As a result, the 88E6060 supports definable frame latencies without head-of-line blocking problems
or non-blocked flow disturbances in any congested environment.
3.6.1
No Head-of-Line Blocking
An output port that is slow or congested never affects the transmission of frames to ports that are not congested.
The 88E6060 device is designed to ensure that all flows that are not congested traverse the switch without degradation regardless of the congestion elsewhere in the switch.
3.6.2
The Queues
The queues in the 88E6060 device are shown in Figure 16.

At reset1, the Queue Manager initializes the Free Queue by setting all of the buffer pointers to point into it and
ensuring that all of the other queues are empty. The Queue Manager then takes the first available free buffer
pointers from the Free Queue and assigns them to any Ingress port that is not disabled2 and whose link3 is up.
When these conditions are met, the switch is ready to accept and switch packets. Whenever any port’s link goes
down or the port is set to the Disabled Port State, the port’s Ingress buffers and Output Queue buffers are immediately returned to the Free Queue. This feature prevents “stale buffers” or “lost buffers” conditions and maximizes
the size of the Free Queue so that of momentary congestion can be handled. When an enabled port’s link comes
back up, the port gets its Ingress Buffers back and it can start receiving frames again.
1. The Queue Manager is reset either by toggling the hardware RESETn pin, a software reset by the SWReset bit, or by an ATUSize
change (both in the ATU Control register–Table 54).
2. When a port is in the Disabled Port State (section 3.5.3), its Ingress buffers are left in the Free Queue for other ports to use.
3. PHY based ports need to get a Link Up signal from the PHY. MII based ports have a link up state if they are enabled.

Functional Description
Queue Controller
When a MAC receives a packet, it places it into the embedded memory at the address indicated by the input pointers that the MAC received from the Queue Manager. When packet reception is complete, the MAC transfers the
pointers to the Queue Manager and requests new buffers from the Free Queue. When the Free Queue is empty,
the MAC is not allocated any pointers until they become available. If the MAC starts to receive a packet when it
has no pointers allocated, the packet is dropped. If flow control is enabled, it prevents this condition from occurring.
The Queue Manager uses the data returned from the Lookup Engine (section 3.4.1) and the Ingress Policy (section 3.5) to determine which Output Queue or Queues the packet’s pointer(s) should go to. At this point, the
Queue Manager modifies the desired mapping of the frame, depending upon the mode of the switch and its level
of congestion.
Two modes are supported, with and without Flow Control. Both modes are handled at the same time and can be
different per port. One port can have Flow Control enabled, while another has it disabled.
When Flow Control is enabled on an ingress port, the frame is switched to the required output queue without modification. This operation is done so that frames are not dropped. The Queue Manager monitors which output
queues are congested and enables or disables flow control on the ingress ports that are causing the congestion.
This approach allows flows that are not congested to progress through the switch without degradation.
When Flow Control is disabled on an ingress port, the frame can be discarded instead of being switched to the
required Output Queue. If a frame is destined for more than one output queue, it can be switched to some queues
and not to others. The decisions are quite complex because the Queue Manager takes many pieces of information
into account before the decision is made.
The Queue Manager monitors the current level of congestion in the Output Queues to which the frame is being
switched, and the current number of free buffers in the Free Queue. As a result, flows that are not congested
traverse the switch unimpeded.
3.6.4
Output Queues
The Output Queues receive and transmit packets in the order received. This is very important for some forms of
Ethernet traffic. The Output Queues are emptied as fast as possible, but they can empty at different rates, possibly
owing to a port's being configured for a slower or faster speed, or because of network congestion (collisions or
Flow Control).
After a packet has been completely transmitted to the MAC, the Output Queue passes the transmitted packet’s
pointers to the Multicast Handler for processing, after which the MAC begins transmitting the next packet.
3.6.5
Multicast Handler
The Multicast Handler receives the pointers from all of the packets that are transmitted. It looks up each pointer to
determine whether each packet were directed to more than one output queue. If not, the pointer is returned to the
Free Queue where it can be used again. When the frame is switched to multiple output queues, the Multicast Handler ensures that the frame has exited all of the ports to which it was switched before returning the pointers to the
Free Queue.

3.7.2
Switch’s Egress Trailer
If a CPU needs to perform Spanning Tree or bridge loop detection, the CPU must have information about the originating physical source ports of its received frames, since those frames' SA information cannot be relied upon. To
get this physical source port data, the CPU’s port needs to be configured for Egress Trailer mode (or egress
header mode—section 3.7.1). Any MII port (Port 4 and Port 5) can be configured this way by setting the TrailerMode bit in the port’s Port Control register (Table 44 on page 94), but only the CPU’s port should be configured
this way.
When the Egress Trailer mode is enabled on a port, four extra bytes are added to the end of the frame before the
frame’s CRC or FCS, and a new CRC is appended to the end of the frame. When the frame is received by the
CPU, the Trailer occupies the last four bytes of the frame. The CPU’s software can examine portions of the frame
to determine if it needs the frame’s source port information. Generally it is needed only on MGMT/Spanning Tree
frames. If the information is not needed, the CPU reduces the frame size variable by four and passes the frame to
the appropriate routines for processing. Removing the Trailer from a frame essentially a subtraction operation
without the need to move any data. Consequently CPU overhead is kept to a minimum.
The format of the Egress Trailer is shown in Figure 17 and its fields are defined in Table 28.

3.8 Spanning Tree Support
IEEE 802.1D Spanning Tree is supported in the 88E6060 device with the help of an external CPU that runs the
Spanning Tree algorithm. The 88E6060 device supports Spanning Tree by:
•
•
•
•
•
Detection of Bridge Protocol Data Unit (BPDU) frames. These frames are called MGMT (management)
frames in the 88E6060 device. They are detected by loading the BPDU’s multicast address
(01:80:C2:00:00:00) into the address database with a MGMT Entry_State indicator (see section 3.4.5.1).
Tunnelling of BPDU frames through Blocked ports. Blocked ports are controlled by the Port’s PortState bits
(section 3.5.3). When a port is in the Blocked state, all frames are discarded except for multicast frames with
a DA that is contained in the address database with a MGMT indicator (see above).
Redirection of BPDU frames. BPDU frames need to go to the CPU only, even though they are multicast
frames. This is handled in the detection of BPDU frames above by mapping the BPDU’s multicast address to
the CPU port. (The value of the DPV bits when the address is loaded).
Source Port information. The CPU needs information of the physical source port of origin of the BPDU frame.
The source port is supplied in the frame’s Egress Trailer that is sent to the CPU (section 3.7.2).
CPU transmission of BPDU frames. The CPU needs to be able to transmit BPDU frames out of any physical
port of the switch. This is supported only in the Ingress Trailer data that is supplied by the CPU (section
3.5.5). The ingress header cannot be used for this since it cannot force MGMT frames to go out a particular
port.
The 88E6060 device can support 802.1D Spanning Tree, or it can be used to perform simpler bridge loop detection on new link up. These different options are accommodated by running appropriate software on the attached
CPU.
Any vendor’s proprietary protocol units can be handled with the same mechanism.
3.9 Embedded Memory
The 88E6060 device contains an embedded 512Kb (8Kx64) Synchronous SRAM (SSRAM). The SSRAM is running at 50 MHz, and the data bus is 64 bits wide. The memory interface provides up to 3.2 Gbps bandwidth for
packet reception/transmission and address mapping data accesses. This memory bandwidth is enough for all the
ports running at full wire speed in full-duplex mode with minimum size frames of 64 bytes.
3.10 Interrupt Controller
The 88E6060 device contains a switch Interrupt Controller that is used to merge various interrupts on to the CPU’s
interrupt signal. Each switch interrupt can be individually masked by an enable bit contained in the Switch Global
Control register (Table 53). When an unmasked interrupt occurs and the interrupt pin goes active low, the CPU
needs to read the Switch Global Status register (Table 49) to determine the source of the interrupt. When the interrupt comes from the switch core (from ATUFull, ATUDone or EEInt), the switch’s interrupt pin goes inactive after
the Switch Global Status register is read. The interrupt status bits are cleared on read. If the interrupt comes from
the PHY (PHYInt), then the switch’s interrupt pin goes inactive only after the PHY’s interrupt is cleared by reading
the appropriate registers in the PHY. See Table 60 for details.

Port Monitoring Support
3.11 Port Monitoring Support
Port monitoring is supported by the 88E6060 device with Egress only monitoring or Egress and Ingress monitoring. Egress monitoring duplicates egress frames from a particular port to a selected monitor port. Ingress monitoring duplicates any good ingress frames for a particular port to a selected monitor port (such frames are processed
normally through the switch). Port monitoring is enabled by modifying the Port Association Vector (Table 46) for
the particular port that is to be monitored.
3.12 Port Trunking Support
Port Trunking is supported by the 88E6060 device with any combinations of ports. The ports that are to be associated with the trunk need to have all the port member’s bits set in each of their Port Association Vectors (Table 46).
Port based VLANs are then used to prevent loops and to load balance the trunk.

The 88E6060 device contains five IEEE 802.3 100BASE-TX and 10BASE-T compliant media-dependent interfaces for support of Ethernet over unshielded twisted pair (UTP) copper cable. DSP-based advanced mixed signal
processing technology supports attachment of up 150 meters of CAT 5 cable to each of these interfaces. An
optional, per port, automatic MDI/MDIX crossover detection function gives true “plug and play” capability without
the need for confusing crossover cables or crossover ports.
The port 0 and port 1 interface can be configured to support IEEE 802.3 100BASE-FX by utilizing a pseudo-ECL

Physical Interface (PHY) Functional Description
Transmit PCS and PMA
4.1 Transmit PCS and PMA
4.1.1
100BASE-TX Transmitter
The 100BASE-TX transmitter consists of several functional blocks that convert synchronous 4-bit nibble data to a
scrambled MLT-3 125 Mbps serial data stream.
4.1.2
4B/5B Encoding
For 100BASE-TX mode, the 4-bit nibble is converted to a 5-bit symbol with /J/K/ start-of-stream delimiters and /T/
R/ end-of-stream delimiters inserted as needed. The 5-bit symbol is then serialized and scrambled.
4.1.3
Scrambler
In 100BASE-TX mode, the transmit data stream is scrambled in order to reduce radiated emissions on the twisted
pair cable. The data is scrambled by exclusive ORing the NRZ signal with the output of an 11-bit wide linear feedback shift register (LFSR), which produces a 2047-bit repeating pseudo-random sequence. The scrambler
reduces peak emissions by randomly spreading the signal energy over the transmit frequency range and eliminating peaks at certain frequencies.
Note
The enabling and disabling of the scrambler and the far end fault generator are controlled in the same way
as for the descrambler detection and far end fault detection on the receive side.
4.1.4
NRZ to NRZI Conversion
The data stream is converted from NRZ to NRZI.
4.1.5
Pre-Driver and Transmit Clock
The 88E6060 device uses an all-digital clock generator circuit to create the various receive and transmit clocks
necessary for 100BASE-TX, 100BASE-FX, and 10BASE-T modes of operation.
For 100BASE-TX mode, the transmit data is converted to MLT-3-coded symbols. The digital time base generator
(TBG) produces the locked 125 MHz transmit clock.
For 100BASE-FX mode, NRZI data is presented directly to the multimode DAC.
For 10BASE-T mode, the transmit data is converted to Manchester encoding. The digital time base generator
(TBG) produces the 10 MHz transmit reference clock as well as the over-sampling clock for 10BASE-T waveshaping.
4.1.6
Multimode Transmit DAC
The multimode transmit digital to analog converter (DAC) transmits MLT3-coded symbols in 100BASE-TX mode,
NRZI symbols in 100BASE-FX mode, and Manchester-coded symbols in 10BASE-T mode. The transmit DAC utilizes a direct-drive current driver which is well balanced to produce very low common mode transmit noise.
In 100BASE-TX mode, the multimode transmit DAC performs slew control to minimize high frequency EMI.

Low Power, 6-port, 10/100 Ethernet Switch
In 100BASE-FX mode, the pseudo ECL level is generated through external resistive terminations.
In 10BASE-T mode, the multimode transmit DAC generates the needed pre-equalization waveform. This preequalization is achieved by using a digital FIR filter.
4.2 Receive PCS and PMA
4.2.1
10-BASE-T/100BASE-TX Receiver
The differential RXP and RXN pins are shared by the 100BASE-TX, 100BASE-FX (supported on Port 0 and Port
1) and 10BASE-T receivers.
The 100BASE-TX receiver consists of several functional blocks that convert the scrambled MLT-3 125 Mbps serial
data stream to the synchronous 4-bit nibble data presented to the MAC interfaces.
4.2.2
AGC and Baseline Wander
In 100BASE-TX mode, after input to the AGC block, the signal is compensated for baseline wander by means of a
digitally controlled Digital to Analog converter (DAC). It automatically removes the DC offset from the received signal before it reaches the input to the sample and hold stage of the ADC.
4.2.3
ADC and Digital Adaptive Equalizer
In 100BASE-T mode, an analog to digital converter (ADC) samples and quantizes the input analog signal and
sends the result into the digital adaptive equalizer. This equalizer removes inter-symbol interference at the
receiver. The digital adaptive equalizer takes unequalized signals from the ADC output and uses a combination of
feed-forward equalizer (FFE) and decision feedback equalizer (DFE) for the best optimized signal-to-noise (SNR)
ratio.
4.2.4
Digital Phased Locked Loop (DPLL)
In 100BASE-TX mode, the receive clock is locked to the incoming data stream and extracts a 125 MHz reference
clock. The input data stream is quantized by the recovered clock and sent through to the digital adaptive equalizer
from each port.
Digital interpolator clock recovery circuits are optimized for MLT-3, NRZI, and Manchester modes. A digital
approach makes the 88E6060 receiver path robust in the presence of variations in process, temperature, on-chip
noise, and supply voltage.
4.2.5
NRZI to NRZ Conversion
In 100BASE-TX mode, the recovered 100BASE-TX NRZI signal from the receiver is converted to NRZ data,
descrambled, aligned, parallelized, and 5B/4B decoded.
4.2.6
Descrambler
The descrambler is initially enabled upon hardware reset if 100BASE-TX is selected. The scrambler can be
enabled or disabled via software by setting the descrambler bit (Table 71).

Physical Interface (PHY) Functional Description
Receive PCS and PMA
The descrambler “locks” to the descrambler state after detecting a sufficient number of consecutive idle codegroups. The receiver does not attempt to decode the data stream unless the descrambler is locked. Once locked,
the descrambler continuously monitors the data stream to make sure that it has not lost synchronization.
The receiver descrambles the incoming data stream by exclusive ORing it with the output of an 11-bit wide linear
feedback shift register (LFSR), which produces a 2047-bit non-repeating sequence.
The descrambler is always forced into the “unlocked” state when a link failure condition is detected or when insufficient idle symbols are detected.
4.2.7
Serial-to-Parallel Conversion and 5B/4B Code-Group
Alignment
The Serial-to-Parallel /Symbol Alignment block performs serial to parallel conversion and aligns 5B code-groups
to a nibble boundary.
4.2.8
5B/4B Decoder
The 5B/4B decoder translates 5B code-groups into 4B nibbles to be presented to the MAC interfaces. The 5B/4B
code mapping is shown in Table 29.
4.2.8.1
FIFO
The 100BASE-X or 10BASE-T packet is placed into the FIFO in order to correct for any clock mismatch between
the recovered clock and the reference clock REFCLK.
4.2.8.2
100BASE-FX Receiver
In 100BASE-FX mode, a pseudo-ECL (PECL) receiver is used to decode the incoming NRZI signal passed to the
NRZI-NRZ decoder. The NRZI signal from the receiver is converted to NRZ data, aligned, parallelized, and 5B/4B
decoded as in the 100BASE-TX mode.
4.2.8.3
Far End Fault Indication (FEFI)
When 100BASE-FX is selected and Bit 0 of CONFIG_A is low at hardware reset, the far end fault detect (FEFD)
circuit is enabled. The FEFD enable state can be overridden by programming the FEFI bit (Table 71).
Note
The FEFI function is always disabled if 100BASE-TX is selected.
4.2.8.4
10BASE-T Receiver
In 10BASE-T mode, the recovered 10BASE-T signal is decoded from Manchester to NRZ and then aligned. The
alignment is necessary to ensure that the start of frame delimiter (SFD) is aligned to the nibble boundary.
In 10BASE-T mode, a receiver is used to decode the differential voltage offset of the Manchester data. Carrier
sense is decoded by measuring the magnitude of the voltage offset.
In this mode, the recovered 10BASE-T signal is decoded from Manchester to NRZ data. The data stream is converted from serial to parallel format and aligned. The alignment is necessary to ensure that the start of frame
delimiter (SFD) is aligned to a byte or nibble boundary. For cable lengths greater than 100 meters, the incoming
signal has more attenuation. Hence, the receive voltage threshold should be lowered via the ExtendedDistance bit
in the PHY Specific Control Register (Table 71).

Setting Cable Characteristics
Since cable characteristics differ between unshielded twisted pair and shielded twisted pair cable, optimal receiver
performance can be obtained in 100BASE-TX and 10BASE-T modes by setting the TPSelect bit in the PHY Specific Control Register (Table 71) for cable type.
4.2.10 Scrambler/Descrambler
The scrambler block is initially enabled upon hardware reset if 100BASE-TX is selected. If 100BASE-FX or
10BASE-T is selected, the scrambler is disabled by default. The scrambler is controlled by programming the DisScrambler bit in the PHY Specific Control Register (Table 71).
The scrambler setting is also controlled by hardware configuration at the end of hardware reset. Table 30 shows
the effect of various configuration settings on the scrambler.

4.2.11 Digital Clock Recovery/Generator
The 88E6060 device uses an all-digital clock recovery and generator circuit to create all of the needed receive and
transmit clocks. The digital time base generator (TBG) takes the 25 MHz or 50 MHz reference input clock
(XTAL_IN) and produces the locked 25 MHz transmit clock for the MAC in 100BASE-TX mode. It produces a 2.5
MHz transmit clock for the MAC in 10BASE-T mode as well as producing the over-sample clock for 10BASE-T
waveshaping.
4.2.12 Link Monitor
The link monitor is responsible for determining whether link is established with a link partner.
In 10BASE-T mode, link monitor function is performed by detecting the presence of the valid link pulses on the
RXP/N pins.
In 100BASE-TX mode, the link is established by scrambled idles.
In 100BASE-FX mode, the external fiber-optic receiver performs the signal detection function and communicates
this information with the 88E6060 device through SDET pin for Port 0 and Port 1.
If Force Link Good is asserted (ForceLink bit is set high - PHY Specific Control Register, Table 71), the link is
forced to be good, and the link monitor is bypassed. Pulse checking is disabled if Auto-Negotiation is disabled,
and DisNLPCheck (PHY Specific Control Register, Table 71) is set high. If Auto-Negotiation is disabled and DisNLPGen (PHY Specific Control Register, Table 71) is set high, then the link pulse transmission is disabled.

4.2.13 Auto-Negotiation
Auto-Negotiation is initiated upon any of the following conditions:
• Power up reset
• Hardware reset
• Software reset (SWReset bit—PHY Control Register, Table 61)
• Restart Auto-Negotiation (RestartAneg bit—PHY Control Register, Table 61)
• Transition from power down to power up (PwrDwn bit—PHY Control Register, Table 61)
• Change from the linkfail state to the link-up state
If Auto-Negotiation is enabled, the 88E6060 device negotiates with its link partner to determine the speed and
duplex mode at which to operate. If the link partner is unable to Auto-Negotiate, the 88E6060 device goes into the
parallel detect mode to determine the speed of the link partner. Under parallel detect mode, the duplex mode is
fixed at half-duplex.
After hardware reset, Auto-Negotiation can be enabled and disabled via the AnegEn bit (PHY Control Register Table 61). When Auto-Negotiation is disabled, the speed and duplex can be changed via the SpeedLSB and
Duplex bits (PHY Control Register - Table 61), respectively. The abilities that are advertised can be changed via
the Auto-Negotiation Advertisement Register (Table 65).
4.2.14 Register Update
Changes to the AnegEn, SpeedLSB, and Duplex bits (Table 65) do not take effect unless one of the following
takes place:
• Software reset (SWReset bit - Table 61)
• Restart Auto-Negotiation (RestartAneg bit - Table 61)
• Transition from power down to power up (PwrDwn bit - Table 61)
• Loss of the link
The Auto-Negotiation Advertisement register (Table 65) is internally latched once every time Auto-Negotiation
enters the ability detect state in the arbitration state machine. Hence, a write into the Auto-Negotiation Advertisement Register has no effect once the 88E6060 device begins to transmit Fast Link Pulses (FLPs). This guarantees that a sequence of FLPs transmitted is consistent with one another.
The Next Page Transmit register (Table 69) is internally latched once every time Auto-Negotiation enters the next
page exchange state in the arbitration state machine.
4.2.15 Next Page Support
The 88E6060 device supports the use of next page during Auto-Negotiation. By default, the received base page
and next page are stored in the Link Partner Ability register - Base Page (Table 66). The 88E6060 device has an
option to write the received next page into the Link Partner Next Page register - Table 70 - (similar to the description provided in the IEEE 802.3ab standard) by programming the Reg8NxtPg bit (PHY Specific Control Register Table 71).
4.2.16 Status Registers
Once the 88E6060 device completes Auto-Negotiation it updates the various status in the PHY Status (Table 72),
Link Partner Ability (Next Page) (Table 67), and Auto-Negotiation Expansion (Table 68) registers. Speed, duplex,
page received, and Auto-Negotiation completed status are also available in the PHY Specific Status (Table 72)
and PHY Interrupt Status registers (Table 74).

The 88E6060 supports advanced power management modes that conserve power.

Two low power modes are supported in the 88E6060.

IEEE 802.3 Clause 22.2.4.1.5 compliant power down
Energy Detect+TM
IEEE 802.3 Clause 22.2.4.1.5 power-down compliance allows for the PHY to be placed in a low-power consumption state by register control.
Energy Detect+TM allows the 88E6060 to wake up when energy is detected on the wire with the additional capability to wake up a link partner. The 10BASE-T link pulses are sent once every second while listening for energy on
the line.
4.3.2 MAC Interface and PHY Configuration for Low Power Modes
The 88E6060 has one CONFIG bit (in CONFIG_B - Table 3) dedicated to support the low power modes.
Low power modes are also register programmable. The EDet bit (Table 71) enables the user to turn on Energy
Detect+™. When the low power mode is not selected, the PwrDwn bit (Table 61) can be used. If during the energy
detect mode, the PHY wakes up and starts operating in normal mode, the EDet bit settings are retained. When the
link is lost and energy is no longer detected, the 88E6060 returns to the mode stored in the EDet bit.

4.3.3 IEEE Power Down Mode
The standard IEEE power down mode is entered by setting the PwrDwn (Table 61 on page 107) bit equal to one.
In this mode, the PHY does not respond to any MAC interface signals except the MDC/MDIO. It also does not
respond to any activity on the CAT 5 cable.
In this power down mode, the PHY cannot wake up on its own by detecting activity on the CAT 5 cable. It can only
wake up by clearing the PwrDwn bit to 0.
4.3.3.1
Energy Detect +TM
In this mode, the PHY sends out a single 10 Mbps NLP (Normal Link Pulse) every second. If the 88E6060 is in
Energy Detect+TM mode, it can wake a connected device and it wakes upon the detection of a connected device.
When ENA_EDET is 1, the mode of operation is Energy Detect+TM.

4.4 Far End Fault Indication (FEFI)
Far-end fault indication provides a mechanism for transferring information from the local station to the link partner
that a remote fault has occurred in 100BASE-FX mode (Port 0 and Port 1 only).
A remote fault is an error in the link that one station can detect while the other one cannot. An example of this is a
disconnected fiber at a station’s transmitter. This station is receiving valid data and detects that the link is good via
the link monitor, but is not able to detect that its transmission is not propagating to the other station.
A 100BASE-FX station that detects this remote fault modifies its transmitted idle stream pattern from all ones to a
group of 84 ones followed by one zero. This is referred to as the FEFI idle pattern.
The FEFI function is controlled by CONFIG_A connection and the DisFEFI bit (Table 71).
Table 32 shows the various configuration settings affecting the FEFI function on hardware reset.

4.5 Virtual Cable Tester™
The 88E6060 PHY Virtual Cable Tester™ feature uses Time Domain Reflectometry (TDR) to determine the quality
of the cables, connectors, and terminations. Some of the possible problems that can be diagnosed include opens,
shorts, cable impedance mismatches, bad connectors, termination mismatches, and bad magnetics.
The 88E6060 Switch Core conducts a cable diagnostic test by transmitting a signal of known amplitude (+1V)
sequentially along each of the TX and RX pairs of an attached cable. The transmitted signal continues along the
cable until it is reflected from a cable imperfection. The magnitude of this echo signal and its return time are shown
in the VCT registers (Table 81 and Table 82) on the AmpRfln and DistRfln bits respectively.
Using the information from these registers, the VCT registers (Table 81 and Table 82), the distance to the problem
location and the type of problem can be determined. For example, the echo time can be converted to distance
using Table 81 and Figure 26 . The polarity and magnitude of the reflection together with the distance indicates the
type of discontinuity. For example, a +1V reflection indicates an open close to the PHY and a -1V reflection indicates a short close to the PHY.
When the cable diagnostic feature is activated by setting the ENVCT bit to one (Table 81), a pre-determined
amount of time elapses before a test pulse is transmitted. This is to ensure that the link partner loses link, so that
it stops sending100BASE-TX idles or 10 Mbit data packets. This is necessary to be able to perform the TDR test.
The TDR test can be performed either when there is no link partner or when the link partner is Auto-Negotiating or
sending 10 Mbit idle link pulses. If the 88E6060 device receives a continuous signal for 125 ms, it declares a test

11 = Test fail (The TDR test could not be run for reasons explained above)
00 = valid test, normal cable (no short or open in cable)
10 = valid test, open in cable (Impedance > 333 ohms)
01 = valid test, short in cable (Impedance < 33 ohms)
The definition for shorts and opens is arbitrary and can be user-defined using the information in the VCT registers
The impedance mismatch at the location of the discontinuity can also be calculated knowing the magnitude of the
echo signal. Refer to the Application Note “Virtual Cable Tester -- How to Use TDR results” for details.
4.6 Auto MDI/MDIX Crossover
The 88E6060 device automatically determines whether or not it needs to interchange cable sense between pairs
so that an external crossover cable is not required. If the 88E6060 device interoperates with a device that cannot
automatically correct for crossover, the 88E6060 PHY makes the necessary adjustment prior to commencing
Auto-Negotiation. If the 88E6060 device interoperates with a device that implements MDI/MDIX crossover, a random algorithm as described in IEEE 802.3 section 40.4.4 determines which device performs the crossover.
When the 88E6060 device interoperates with legacy 10BASE-T devices that do not implement Auto-Negotiation, it
follows the same algorithm as described above since link pulses are present. However, when interoperating with
legacy 100BASE-TX devices that do not implement Auto-Negotiation (i.e. link pulses are not present), the
88E6060 device uses signal detection to determine whether to implement crossover.
The Auto MDI/MDIX crossover function can be disabled via the AutoMDI[X] bits (Table 71).
The 88E6060 device is set to normal mode by default if auto MDI/MDIX crossover is disabled at hardware reset.
The pin mapping in normal and crossed modes is specified in Table 33.

4.7 LED Interface
The LED interface pins can either be controlled by a port’s PHY or controlled directly, independently of the state of
the PHY. Four display options are available and both interfaces (PHY or direct control) can be used together to
provide even more LED combinations.
The LEDs can be controlled through a parallel interface or via a serial interface that supports up to seven LEDs
per port.
Direct control of the parallel LEDs is achieved by writing to the PHY Manual LED Override register (Table 80). Any
of the parallel LEDs can be turned on, off, or made to blink at variable rates independent of the state of the PHY.
When the parallel LEDs are controlled by a port’s PHY, their activity is determined by the PHY’s state. Each LED
can be programmed to indicate various PHY states, with variable blink rate.
Some port PHY events configured to drive LED pins are too short to result in an observable change in LED state.
For these events, pulse stretching is provided to translate a short PHY event into an observable LED response.
The duration of a pulse stretch can be programmed via the PulseStretch bits (Table 79). The default pulse stretch
duration is set to 170 to 340 ms. The pulse stretch duration applies to all applicable LED interface pins.
Some of the status indicators signal multiple events by toggling LED interface pins resulting in a blinking LED. The
blink period can be programmed via the BlinkRate bits (Table 79). The default blink period is set to 84 ms. The
blink rate information is true for all applicable LEDs.
4.7.1
Parallel LED Interface
These LED interface pins can be used to display port status information. The LED interface has three different status indicators for each port with four different default display options, using the Px_LED2, Px_LED1, and Px_LED0
pins.The LED Parallel Select Register (Table 77) specifies which single LED mode status to display on the LED
interface pins. The default display for each mode is shown in Table 34 and the default mode that applies depends
upon the hardware configuration established using the CONFIG_A pin—see Table 3.

4.7.2
Serial LED Interface
The LEDSER, LEDENA, and LEDCLK pins are used for the serial interface. The CONFIG_A pin (see Table 3) is
used to select one of four possible default LED modes which are numerically the same as those set up by the
CONFIG_A pin in the parallel case.
However, the default displays in this case are different. The serial LED interface can display a variety of different
status indications in 100BASE-TX and 10BASE-T modes (see Table 37 and Table 38). Status to display, pulse
stretching, and blink speed can be programmed via the LED Stream Select for Serial LEDs register (Table 78)
4.7.2.1
Single and Dual LED Modes
Single LED mode is initiated at power up according to the CONFIG_A pin settings. Dual LED mode can be
entered (or single mode can be reentered) by setting the appropriate register fields according to Table 78. These
registers enable LED functions to be programmed individually in dual LED or single LED mode. The data states
are sent out on the LEDSER data stream and may be extracted using the LEDCLK and LEDENA signals as
shown in the example of Figure 20.
4.7.2.2
Single LED Modes
In the single LED display mode, the same status is driven on both status 100 and status 10 positions in the bit
stream. However, the LEDENA signal asserts only over the status that is set and de-asserts over the other position that is turned off in the bit stream. For example, DUPLEX shows the same status for DUPLEX100 and
DUPLEX10. However, the LEDENA signal is high over Duplex100 position only for one clock period. Refer to
Figure 20 for more details.
4.7.2.3
Dual LED Display Mode
In the dual LED display mode, two LEDs are used: one for 10 Mbps, and one for 100 Mbps activity. A different status is driven on status 100 and status 10 positions in the bit stream. In this case, the LEDENA signal asserts over
both 100 and 10 positions in this stream. For example, the LEDENA signal asserts over COLX100 and COLX10 in
Figure 20. and remains high for two clock periods. If one of these status bits (shown in Table 38) is turned off,
LEDENA is not asserted in both positions.

LED Interface
The bit stream on LEDSER can be clocked into a shift register with LEDENA as the shift enable signal as shown
in Figure 21. The rate of update of the serial LED interface is controlled by programming register 24.8:6. The
default value is set to 42 ms.

After the LED data is shifted into the correct position, the shift sequence is suspended to allow the appropriate
LEDs to light or extinguish depending on status. The LED implementation used in the 88E6060 device is self-synchronizing. The default display options are given in Table 36.

The LED status bits are output in the order shown on the LEDSER pin synchronously with LEDCLK. All status signals for Port 5 are sent out first followed by those for Ports 4 through 0. Each bit in the stream occupies a period of
80 ns.

Serial Management Interface (SMI)
MDC/MDIO Read and Write Operations
Section 5. Serial Management Interface (SMI)
The 88E6060 serial management interface provides access to the internal registers via the MDC and MDIO signals and is compliant with IEEE 802.3u clause 22. MDC is the management data clock input whose frequency can
run from DC to a maximum rate of 8.3 MHz. MDIO is the management data input/output which carries a bidirectional signal that runs synchronously with the MDC. The MDIO pin requires a pull-up resistor to pull the MDIO high
during idle and turnaround times.
5.1 MDC/MDIO Read and Write Operations
All of the relevant serial management registers, as well as several optional registers, are implemented in the
88E6060 Switch Core. A description of these registers can be found in Section 6. "Switch Register Description" .
Note
Access to the 88E6060 device’s Switch and PHY registers is not possible when the Serial EEPROM is still
loading the registers. A CPU can monitor the 88E6060 device INTn pin, which will go active (low) when
the Serial EEPROM has been fully processed (i.e., a Halt instruction has been reached - see section 8).

Switch Register Description
Section 6. Switch Register Description
All of the 88E6060 registers are accessible using the IEEE Serial Management Interface (SMI) used for PHY
devices (see MDC/MDIO pin description in Section 1 and Section 5 of this datasheet). The 88E6060 device uses
16 of the 32 possible Device Addresses. The16 Device Addresses are configurable at reset by use of the
EE_CLK/ADDR4 pin (see Signal Description in part 1 of this datasheet). Figure 25 shows the register map assuming the lower 16 SMI Device Addresses are being used.

6.1 Register Types
The registers in the 88E6060 device are made up of one or more fields. The way in which each of these fields
operate is defined by the field’s Type. The function of each Type is described in Table 40.
Table 40:
Register Types
Typ e
Desc ription
LH
Register field with latching high function. If status is high, then the register is set to a one and
remains set until a read operation is performed through the management interface or a reset
occurs.
LL
Register field with latching low function. If status is low, then the register is cleared to a zero and
remains cleared until a read operation is performed through the management interface or until a
reset occurs.
RES
Reserved for future use. All reserved bits are read as zero unless otherwise noted.
RO
Read only.
R/W
Read and write with no definable initial value
RWR
Read/Write reset. All bits are readable and writable. After reset the register field is cleared to zero.
RWS
Read/Write set. All bits are readable and writable. After reset the register field is set to a non-zero
value specified in the text.
SC
Self-Clear. Writing a one to this register causes the required function to be immediately executed,
then the register field is cleared to zero when the function is complete.
Update
Value written to the register field does not take effect until a soft reset is executed.
Retain
Value written to the register field D0
WO
Write only. Reads to this type of register field return undefined data.
6.2 Switch Core Registers
Switch Core Registers are of two types:
•
Switch Port Registers—are separately configured for each port comprised in the switch. Each port has a
unique associated SMI device address and this address is used to access that port’s switch register set.
• Switch Global Registers—are configured using a single SMI device address. A global register’s setting
affects all ports of the switch.
The 88E6060 contains six ports (MACS). The supported ports are accessible using SMI device addresses 0x08 to
0x0D, or 0x18 to 0x1D depending upon the value of the EE_CLK/ADDR4 pin at reset (Section 1). The MACs are
fully IEEE802.3 compliant. Since there is no IEEE standard covering required MAC registers, these registers are
88E6060 device specific.
The switch contains many global registers that are used to control features and functions that are common to all
ports in the switch. The global registers are accessible using SMI device address 0x0F (or 0x1F) depending upon
the value of the EE_CLK/ADDR4 pin at reset.

The PortMode, PHYMode, Duplex, and Speed bits for Port 5 and Port 4 come from the Px_MODE[3:0] pins at
reset (if Port 4 is in MII mode). When the PortMode is a one, the PHYMode, Duplex, and Speed bits map the same
as the other 10/100 ports that contain PHYs. When the PortMode is a zero the mapping is easier to see by looking
at "RMII/MII/SNI Configuration" Table 19:.

PortState
RWR
Port State. These bits are used to manage a port to determine what kind of
frames, if any, are allowed to enter or leave a port for simple bridge loop
detection or 802.1D Spanning Tree. The state of these bits can be changed
at any time without disrupting frames currently in transit. The Port States are:
Or
RWS to
0b11
00 = Disabled. The switch port is completely disabled and it will not receive
or transmit any frames. The QC will return any pre-allocated ingress
queue buffers when the port is in this mode.
01 = Blocking/Listening. The switch will examine all frames without learning
any SA addresses, and discard all but MGMT frames. MGMT (management) frames are the only kind of frame that can be tunneled
through Blocked ports. A MGMT frame is any frame whose multicast
DA address appears in the ATU Database with the MGMT Entry
State. It will allow MGMT frames only to exit the port. This mode is
used for BPDU handling for bridge loop detection and Spanning Tree
support.
10 = Learning. The switch will examine all frames, learning all SA addresses,
and still discard all but MGMT frames. It will allow MGMT frames only
to exit the port.
11 = Forwarding. The switch will examine all frames, learning all SA
addresses, and receive and transmit all frames like a normal switch.
The PortState bits for all ports come up in the Forwarding state unless the
SW_MODE[1:0] pins are set to 0b00, the CPU attached mode.
Software Reset, (SWReset - Table 54 on page 102) causes the PortState bits
to revert back to their reset state (i.e., either Disabled or Forwarding).

Register 0x05 (Hex), or 5 (Decimal) is reserved.

Port based VLAN Table. The bits in this table are used to restrict which output
ports this input port can send frames to. These bits restrict where a port can
send frames to (unless a VLANTunnel frame is being received - see Port
Control register, Table 44).
To send frames to Port 0, bit 0 of this register must be a one. To send frames
to Port 1, bit 1 of this register must be a one, etc. After reset, all ports are
accessible since all the other port number bits are set to a one. This Port’s bit
will always be zero at reset. This prevents frames exiting the port on which
they arrived. This port’s bit can be set to a one in the 88E6060 Switch Core
enabling frames to be returned on their ingress port; consequently care
should be taken in writing code to control these bits.
This register is reset to 0x3E for Port 0 (SMI Device Address 0x8), and it
resets to 0x3D for Port 1 (Addr 0x9) and to 0x3B for Port 2 (Addr 0xA), etc.

these bits contain a non-zero value. When these bits are all zero automatic
Learning and Entry_State refresh is disabled on this port.
For normal switch operation this port’s bit should be the only bit set in the
vector. These bits must only be changed when frames are not entering the
port (see PortState bits in Port Control – Table 44, on page 94).
The PAV bits can be used to set up an egress port monitor. To configure Port
0 to receive a copy of the frames that exit Port 1, set bit 0 in Port 1’s PAV register (along with Port 1’s bit). To configure Port 0 to get a copy of the frames
that exit Port 2, set bit 0 in Port 2’s PAV register, etc.
The PAV bits can be used to set up an ingress port monitor along with an
egress port monitor. To configure Port 0 to receive a copy of the frames that
enter Port 1 as well as exit Port 1, set bit 0 in Port 1’s PAV register (along
with Port 1’s bit—bit 1) and set the IngressMonitor bit above.
The PAV bits can be used to set up port trunking (along with the VLANTable
bits (Table 45 on page 96). For the two ports that form a trunk, set both of the
port’s bits in both port’s PAV registers. Then use the VLANTable to isolate the
two ports from each other and to steer the traffic from the other ports down
the required trunk line of the pair.

4. A Get Next operation finds the next higher MAC address currently in a particular ATU database (defined by the DBNum field). The
ATUByte[5:0] values (Table 57, on page 104) are used as the address to start from. To find the lowest MAC address set
ATUByte[5:0] to ones. When the operation is done ATUByte[5:0] contains the next higher MAC address found. To find the next
address simply issue the Get Next opcode again. If ATUByte[5:0] is returned set to all ones, no higher MAC address was found (if
EntryState = 0) or the Broadcast Address was found (if EntryState ≠ 0) In either case, the end of the table was reached. To Search
for a particular address, perform a Get Next operation using a MAC address with a value one less than the one being searched for.

PHY Software Reset
Writing a 1 to this bit causes the PHY state machines to
be reset. When the reset operation is done, this bit is
cleared to 0 automatically. The reset occurs immediately.

Enable Loopback Mode
When loopback mode is activated, the transmitter data
presented on TXD is looped back to RXD internally. The

Speed Selection (LSB)
When a speed change occurs, the PHY drops link and
tries to determine speed when Auto-Negotiation is on.
Speed, Auto-Negotiation enable, and duplex enable take
on the values set by ANEG[2:0] on hardware reset. A
write to these registers has no effect unless any one of
the following also occurs:
Software reset is asserted (bit 15) or
Power down (bit 11) transitions from power down to normal operation.

write to these registers has no effect unless any one of
the following also occurs:
Software reset is asserted (bit 15, above), Power down
(bit 11, below), or transitions from power down to normal
operation.
If the AnegEn bit is set to 0, the speed and duplex bits of
the PHY Control Register (Offset 0x00) take effect.
If the AnegEn bit is set to 1, speed and duplex advertisement is found in the Auto-Negotiation Advertisement
Register (Offset 0x04).
1 = Enable Auto-Negotiation Process

The amplitude of reflection is stored in these register
bits. These amplitude bits range from 0x07 to 0x1F.
0x1F = Maximum positive amplitude
0x13 = Zero amplitude

EEPROM Programming Format
EEPROM Programming Details
Section 8. EEPROM Programming Format
8.1 EEPROM Programming Details
The 88E6060 device supports an optional external serial EEPROM device for programing its internal registers.
The EEPROM data is read in once after RESETn is deasserted if the stand alone Switch Mode is not selected
(see Table 14 on page 29).
The 88E6060 supports 1K bit (93C46), 2K bit (93C56), or 4K bit (93C66) EEPROM devices. The size of the device
is selected by the EE_DIN/EE_1K pin at reset—see Table 7 on page 21. The external EEPROM device must be
configured in x16 data organization mode.
Regardless of which particular device is attached, the EEPROM is read and processed in the same way:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Start at EEPROM address 0x00.
Read in the 16 bits of data from the even address. This step is called the Command.
If the just read in Command is all ones, terminate the serial EEPROM reading process and go to step 8.
Increment the address by 1—to the next address.
Read in the 16 bits of data from that address—This is called the RegData.
Write RegData to the locations defined by the previous Command.
Go to step 2.
Set the EEInt bit in Global Status to a one (Table 49, on page 99) generating an Interrupt (if enabled).
Done.
The 16-bit Command determines which register or registers inside the 88E6060 are updated as follows. Refer to
Figure 27 below.
•
Bit 15 determines which set of registers can be written.
If bit 15 = 0 the PHY registers can be written (SMI Device Addresses 0x00 to 0x04) or the Switch Global registers can be written (SMI Device Address 0x7).
If bit 15 = 1 the Switch registers can be written (SMI Device Addresses 0x08 to 0x0D). See section 6 and
Figure 25 for more information on the registers and their addresses.
•
Bits 10:5 (or 9:5), the Device Vector, determines which Device Addresses are written. Each bit of the Device
Vector that is set to a one causes one Device Address to be written. Bit 5 controls writes for Port 0 (either
PHY address 0x00 or Switch address 0x08).
Bit 6 controls writes for Port 1 (either PHY address 0x01 or Switch address 0x09).
Bit 7 controls writes for Port 2, etc.
The Switch Global registers (Switch address 0x0F) are written when bit 15 is a zero and bits 14:5 are ones.
Care is needed to ensure that Reserved registers are not written.
Bits 4:0, the Register Address, determine which SMI Register Address is written.

The format of the EEPROM Commands supports writing the same RegData to all the PHYs or all the Switch’s
MACs with one Command/RegData pair. The Command/RegData list can be as short or as long as needed. This
makes optimum use of the limited number of Command/RegData pairs that can fit in a given size EEPROM1. The
maximum number of Command/RegData pairs is one fewer than might be expected from a simple calculation
because the last entry must be the End of List or Halt Indicator of all ones.
