The PM3386 is a dual channel SERDES and GMAC with embedded FIFOs that provides a high density and low power Gigabit Ethernet solution for direct connection to electrical optical modules. Alternatively, a GMII interface is provided for connection to copper Gigabit Ethernet physical layer devices. On the system side, the POS-PHY Level 3 (32 bit synchronous FIFO style interface clocked up to 104 MHz) allows a common connection to higher layer devices. A common system interface simplifies multi-service equipment utilizing some or all of the following physical layer options: • OC-48 POS/ATM • 4xOC-12 POS/ATM • 16xOC-3 POS/ATM • Channelized POS/ATM • High density DS3 • Gigabit Ethernet The PM3386 is particularly suited for the following applications: • Core Routers • Edge Routers • Enterprise Edge Routers • Multi-Service Switches/Routers • SONET/SDH Transport Muxes These applications require various interfaces (Gigabit Ethernet, ATM, POS, DS3) which use the POS-PHY Level 3 interface. Service cards for various physical layer options can re-use upper layer devices and board design to improve timeto market. The use of Gigabit Ethernet within Internet points of presence (POPs), Super POPs and Transport POPs is increasing due to the requirement of inexpensive high-speed Layer 2 interconnect. Thus, connections between PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 7 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER Edge Routers and Core Routers within a POP are provided via Gigabit Ethernet. Co-located server clusters are also connected via Gigabit Ethernet to POP routers. Similarly, Gigabit Ethernet is becoming the choice for connection between Enterprise Routers and Multi-Service switches. Transport equipment is looking to provide Ethernet directly over SONET/SDH for wide area transparent bridging. In a typical application the S/UNI-2xGE performs data recovery on the Gigabit Ethernet stream, MAC level frame checks and sends the frame to an upper layer device (such as an IP processor) for forwarding via the POS-PHY level 3 interface. The S/UNI-2xGE maintains extensive statistics for SNMP and RMON applications. On egress, frames are formatted into physical frames with the proper inter-frame gap, preamble and start of frame delimiter. The physical packet is then serialized for transmission over an external electrical optical module. The initial configuration and ongoing control and monitoring of the S/UNI-2xGE are provided via a generic microprocessor interface. The following diagram shows a typical multi-service card application for the PM3386 S/UNI2xGE with similar cards for OC48 and Quad OC-12 ports.

The PM3386 provides line interface connectivity provided by an on-chip SERDES and GMII functions and data transport to the up stream device via the industry standard POS-PHY Level 3 interface. Serializer-Deserializer (SERDES) The PM3386 has two internal serializer-deserializer transceivers. The SERDES are IEEE 802.3-1998 Gigabit Ethernet compatible supporting gigabit data transfer flows. The SERDES is based on the X3T11 10 Bit specification. The PM3386 receives and transmits Gigabit Ethernet streams using a bit serial interface for direct connection to optical transceiver devices. The SERDES performs data recovery and serial to parallel conversion for connection to the Enhanced Gigabit Media Access Control block. Gigabit Media Independent Interface (GMII) For Gigabit Ethernet over copper support, the PM3386 provides dual standard GMII interfaces. A copper Gigabit Ethernet physical layer device can be connected to the PM3386 via this interface. Enhanced Gigabit Media Access Control (EGMAC) The Enhanced Gigabit Media Access Control (EGMAC) block provides an integrated IEEE 802.3-1998 Gigabit Ethernet Media Access Control (MAC) supporting high performance 1000Base capability. The EGMAC has line side interfaces for connection to internal (SERDES) and external Gigabit PHY via GMII on each Gigabit Ethernet port. The Enhanced Gigabit MAC (EGMAC) incorporates all of the Gigabit Ethernet MAC functions including AutoNegotiation, statistics, and the MAC Control Sub-layer that adheres to IEEE 802.3-1998 providing support for PAUSE control frames. The EGMAC provides basic frame integrity checks to validate incoming frames. The EGMAC also provides simple line rate ingress address filtering support via 8 exact-match MAC address and VID unicast filters, one 64-bin hash-based multicast filter, and the ability to filter or accept matched frames on a per instance programmable fashion. All inquires for filtering are done at line rate with no system latency introduced for look up cycles. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 12 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER Management Statistics (MSTAT) The PM3386 also incorporates a rich set of per port RMON, SNMP, and Etherlike Management Information Base counters. Deep statistical counters are used for management counts providing a minimum rollover time of greater than 58 minutes. All counts are easily managed via the Management Statistics (MSTAT) block. POS-PHY Level 3 Interface (PL3) The PM3386 can connect to a single upper layer device through a POS-PHY Level 3 Interface. The POS-PHY Level 3 interface is a 32-bit wide interface with a clock rate from 60 to 104 MHz. POS-PHY Level 3 was developed with the cooperation of the SATURN Development Group to cover all application bit rates up to and including 3.2 Gbit/s. This interface provides standards support for interoperation between the PM3386, a multiple PHY layer device, connecting to one Link Layer device. The interface stresses simplicity of operation to allow forward migration to more elaborate PHY and Link Layer devices. The POSPHY interface contains 64KB receive and 16KB transmit FIFOs per channel. These FIFOs contain programmable thresholds specifying full and empty conditions. Receive Direction In the receive direction, the PM3386 can be configured to use the internal SERDES or the GMII interface on a per channel basis. For SERDES operation, a Gigabit Ethernet bit stream is received from an external optical transceiver. The data is recovered and converted from serial to parallel data for connection to the EGMAC block. The EGMAC terminates the 8B/10B line codes and performs frame integrity checks (frame length, FCS etc). For GMII operation, the physical packet is sourced from an external copper physical layer device to the PM3386 via the GMII interface (8 bits clocked at 125 MHz). The EGMAC accepts the 8 bit data and performs frame integrity checks once the complete frame is received. The EGMAC can optionally filter erred frames. Statistics are updated and the frame is sent to the POS-PHY Level 3 interface. The FIFO’s in the POS-PHY interface accommodate system latencies and allows for loss-less flow control up to 9.6k bytes. The received frames are then read through the POS-PHY Level 3 (32 bits clocked from 60-104 MHz) system side interface. Transmit Direction In the transmit direction, packets to be transmitted are written into the POS-PHY TX FIFO through the POS-PHY Level 3 interface (32 bits clocked from 60-104 PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 13 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER MHz) from the upper layer device. The channel is selected by the upper layer device and is indicated in-band on the POS-PHY interface. The EGMAC builds a properly formatted Ethernet physical packet (padding to minimum size and inserting the preamble, start of frame delimiter (SFD) and the inter-packet gap (IPG)). Statistics are updated and the physical packet is sent to the SERDES or the GMII interface. For SERDES operation, the EGMAC encodes the physical packet using 8B/10B encoding and passes the physical packet to the SERDES block. The SERDES performs parallel to serial conversion using an internally synthesized 1250 MHz clock. The bit stream is sent to an external optical transceiver for transmission over fiber cable. For GMII operation, the EGMAC sends the physical packet byte by byte across the GMII interface (8 bits clocked at 125 MHz) to an external copper Gigabit Ethernet physical layer device. The copper Gigabit Ethernet physical layer device then transmits the physical packet over copper cable. Flow Control Flow control is handled in the EGMAC block. When a PAUSE control frame is received, the PM3386 will optionally terminate transmission (after the current frame is sent) and assert the appropriate channel side band flow control output to indicate the paused condition. The received PAUSE control frame can be optionally filtered or passed to the link layer device via the POS-PHY Level 3 interface. PAUSE control frames are transmitted either under link layer control using channel side band flow control inputs, under link layer control transparent to the PM3386, host based PAUSE frame control or under internal control based on receive FIFO levels. All four methods can provide for loss-less flow control. General The PM3386 is configured, controlled and monitored via a generic 16-bit microprocessor bus interface. The PM3386 also provides a standard 5 signal IEEE 1149.1 JTAG test port for boundary scan board test purposes. The PM3386 is implemented in low power, +1.8 Volt, CMOS technology with 5V TTL compatible digital inputs and 3.3V TTL/CMOS compatible digital outputs.

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 42 PM3386 RELEASED DATASHEET PMC-1991129 10 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER FUNCTIONAL DESCRIPTION The PM3386 provides a high density and low power solution for implementing Gigabit Ethernet connectivity. The PM3386 is a dual Gigabit Ethernet controller with integrated SERDES and GMAC functions connecting to a standard POSPHY Level 3 system interface. The PM3386 accepts serial bit streams from optical transceiver devices or Gigabit Ethernet PHY devices and performs Media Access Control frame verification. Statistics are maintained and the frame is forwarded to internal FIFOs for the POS-PHY Level 3 interface. The PM3386 may be connected to an upper layer device via the POS-PHY Level 3 interface for classification and forwarding. The PM3386 is partitioned into the following major functional blocks. The operation of each block is described in more detail in subsequent sections. 10.1 • SERDES • Enhanced Gigabit Media Access Control • Ethernet Statistics • Address Filtering • POS-PHY Level 3 System Interface • Microprocessor Interface Serializer-Deserializer (SERDES) The PM3386 has two internal serializer-deserializer transceivers. The SERDES is IEEE 802.3-1998 Gigabit Ethernet compatible supporting gigabit data transfer flows. The SERDES is based on the X3T11 10 Bit specification. The PECL cells used to implement the SERDES are capable of both 5V and 3.3V low voltage PECL operation as they can be AC coupled within the system design. The transmitter section of the SERDES accepts 10-bit wide parallel data and serializes this data into a high-speed serial data stream. The parallel data is 8B/10B encoded data. An internally generated reference clock is then multiplied to generate the 1250 MHz serial clock used to clock the encoded data out the high-speed output at a rate of 1250 Mbit/s. The high-speed outputs are capable of interfacing directly to a separate fiber optic module for optical transmission. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 43 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER The receiver section accepts a serial electrical data stream at 1250 Mbit/s and recovers the original 10-bit wide parallel data. The receiver Clock Recovery Unit (CRU) locks onto the incoming serial signal and facilitates the recovery of the high-speed serial data. The serial data is converted back into 10-bit parallel data, recognizing the 8B/10B comma character to establish byte alignment. The recovered parallel data is presented to the EGMAC. 10.2 Enhanced Gigabit Media Access Control (EGMAC) 10.2.1 EGMAC General The PM3386 integrates standard IEEE 802.3-1998 Gigabit Ethernet Media Access Control interfaces for connection to internal serializer-deserializers (SERDES) or external transceivers using Gigabit Media Independent Interface (GMII) pins on each gigabit Ethernet port. The dual ports of the PM3386 are capable of operation in either SERDES or GMII mode. The ports can be configured to operate independently from each other using the PMD_SEL0 and PMD_SEL1 pins. The EGMAC is capable of supporting normal Ethernet frame sizes of 1518 bytes, VLAN tagged frame sizes of 1522 bytes, and Jumbo frames sizes up to 9.6k bytes. The Transmit Max Frame Length and the Receive Max Frame Length registers contain the values associate with maximum accepted Ethernet frame sizes. By default these registers contain a value of 1518 bytes. This allows for normal frame sizes as well as 1522 VLAN tagged frames to be accepted. The EGMAC will base all frame length calculations and statistics off of these registers. The EGMAC takes into account the VLAN tagging of frames to ensure their proper representation in the statistics gathering process. Note that it is possible to program the ingress and egress maximum frame sizes separately. 10.2.2 EGMAC Egress Direction In the egress direction packet data from the PL3EP is presented to the EGMAC synchronizing transmit FIFO. The EGMAC/PL3EP interface is a push style interface. If packet data is available for transmit the PL3EP will push (transfer) data to the EGMAC. The PL3EP will notify the EGMAC of the start and end of packets by using simple end of packet and start of packet indications. The PL3EP will also present to the EGMAC an error signal that is asserted when an error condition is observed on the POS-PHY bus or if an internal error is encountered in the egress data path. The EGMAC has an upper bound of 9.6k bytes on the size of egress frames. The egress direction of the EGMAC can accept packets of a minimum size of 14 bytes. Egress packets sent to the EGMAC that are of the minimum 14 bytes but PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 44 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER are less than the minimum 64 byte frame length required by 802.3-1998 have the programmed option to be padded appropriately to 64 bytes (68 bytes for VLAN tagged frames) and optionally have the associated 32 bit CRC appended to the frame prior to transmit. The user may also elect to program the EGMAC to insert the Frame Check Sequence (FCS) field. In the case that the link device disregards the flow control information provided by DTPA0, DTPA1, STPA, or PTPA and continues to write to the PM3386 in an attempt to overflow the egress FIFO the PM3386 will truncate the current packet when the FIFO becomes full. At this time the PM3386 will wait until a minimum packet can be accepted and then resume data transfer. In the event that the link device can not deliver the data fast enough to the PM3386, placing the PM3386 in a case of FIFO underrun, the current packet will be truncated sending all bytes currently available and then the PM3386 will resync to TSOP. In all error cases the CRC-32 that is kept over the packet will be invalidated and appended to the frame as it is transmitted thereby signaling an error. Following each frame transmission the EGMAC provides a statistical vector to the MSTAT block that updates statistic collection counters maintained in system visible registers. Please refer to the MSTAT functional description and Register section of this document for a full list of port statistics. 10.2.3 EGMAC Ingress Direction In the ingress direction the SERDES or GMII presents receive physical packet to the EGMAC. The EGMAC scans the preamble looking for the Start Frame Delimiter (SFD). By default the preamble and SFD are stripped converting the physical packet to a frame. The EGMAC will then compare the destination address in the frame to the address filtering logic for the given port. If enabled the address filtering logic may be programmed to accept or reject incoming frames. The EGMAC is also programmable to accept all frames regardless of validity. The EGMAC supports ingress frame sizes of up to 9.6k bytes. The EGMAC interfaces to the PL3IP using a simple push style interface. The EGMAC signals start of frame and end of frame while transferring data information to the PL3IP. There are two decision points at which the frame forwarding and filtering decisions are made. The first decision point is at the beginning of the ingress frame. At this point and once the SA, DA, and the possible VID fields are recognized the frame may be filtered based on the address filter logic described later. If the frame is to be forwarded the incoming data will be written to the PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 45 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER EGMAC ingress FIFO in preparation for frame transfer. If the frame is to be filtered the frame will not be written to the EGMAC FIFO and the EGMAC will resync to the next incoming ingress frame. The second decision point is at the end of the frame. The EGMAC will perform frame integrity checks such as length and CRC. If the frame violates these integrity checks the frame will need to be discarded. Discarding a frame can be done in two possible ways. The cases are described below. 1. If the number of bytes that have been written to the EGMAC ingress FIFO are less than the programmed value within the EGMAC Receive FIFO Forwarding Threshold register, the frame in its entirety is stored within the FIFO, and will therefore be dropped within the EGMAC. The EGMAC will flush this frame from the FIFO and resume reception of ingress traffic on the next start of frame indication. 2. If the number of bytes that have been written to the EGMAC ingress FIFO are greater than the programmed value within the EGMAC Receive FIFO Forwarding Threshold register the frame will have started draining from the FIFO and therefore can not be dropped within the PM3386. In this case the frame will be marked as bad by assertion of the RX_ERR bit on the EGMAC PL3IP interface. This indication is carried to the POSPHY Level 3 interface and will cause the assertion of the RERR bit on the last byte transfer of the packet. As mentioned above ingress frames are held in the receive FIFO within the EGMAC until the byte count exceeds the forwarding threshold programmed in the EGMAC Receive FIFO Forwarding Threshold register or until End Of Frame (EOF). Frames that contain errors and are greater than the programmed value within the EGMAC Receive FIFO Forwarding Threshold register will be marked as erred by the PM3386 but will not be discarded within the PM3386. The EGMAC will distinguish between unicast, broadcast, and multicast frames. The EGMAC can be programmed to forwarded or filter frames based on unicast, broadcast, or multicast type frames. 10.2.4 EGMAC Flow Control - MAC Control Sublayer The PM3386 provides loss-less frame flow control for frame sizes up to 9.6k bytes over 1000BASE TX, 1000BASE SX, and 1000BASE LX implementations. The EGMAC interface contains the MAC Control Sublayer which adheres to IEEE 802.3-1998 and provides support for Control frames. The EGMAC performs the functions out lined in IEEE 802.3-1998 Clause 31 “MAC Control” and Annexes 31A and 31B. Clause 31 introduces the optional MAC Control PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 46 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER sublayer to the popular layer stack. This sublayer provides for real-time control and manipulation of the MAC operation. The clause defines MAC control frames distinguishable by their unique Length/Type field identifier. The EGMAC supports Annex 31A opcode PAUSE by implementing Annex31B’s frame based flow control scheme which utilizes PAUSE Control frames. The purpose of flow control is to slow down the aggregate rate of frames that the other end of a link is sending. Finite FIFO depths have a tendency to overflow when line-rate frames are being received and the upper layer device cannot keep up. Thus to prevent the overflow of the FIFOs, flow control is used. A MAC Control client wishing to inhibit transmission of data frames from the PM3386 generates a PAUSE Control frame which contains the reserved multicast address (01-80-C2-00-00-01), the Control frame type field 88-08, the PAUSE opcode, 00-01, and the pauseTimer, a 16-bit value expressed in pause quanta of 512 bit times. When the EGMAC receives a PAUSE Control frame, it loads the Pause Timer with the value sent in the pauseTime filed. If pauseTime is nonzero and the FCRX bit within the EGMAC GMACC1-Config Register is asserted, the EGMAC will pause from transmitting frames and will wait for pauseTime number of slot times before resuming operation. If, however, the pauseTime value is equal to zero, the EGMAC is allowed to resume transmitting data frames. At any time if the EGMAC is receiving PAUSE control frames the EGMAC will assert the PAUSED0 or PAUSED1 status pins. These pins will be held asserted until the EGMAC pauseTime counts down to zero and the EGMAC resumes transmitting data frames. It is possible depending on the system requirements to allow ingress PAUSE Control frames to be processed or not processed at the EGMAC layer (see FCRX bit) and PAUSE Control frames to be dropped at the EGMAC layer or passed to the upper layer device(see PASS_CTRL bit). If for any reason the upstream device needs to stop incoming frames, it can accomplish this by four different ways. First, the upper layer device can send 802.3-1998 PAUSE Control frames of its own. Second, the upper layer device can assert the PAUSE0 or PAUSE1 pins on the device to have the EGMAC automatically send PAUSE Control frames. Third, the system processor can initiate PAUSE operation via configuration registers in the EGMAC. Fourth, the link device can de-assert RENB and cause the FIFO fill levels in the PL3IP block to fill and start automatic flow control. Note that even though the EGMAC can be sending egress PAUSE Control frames the ingress channel will still be operational with the exception of normal blocking of the POS-PHY L3 data-path from the link level. Please refer to the Operations section under PAUSE Flow Control for programming options. At the end of a PAUSE operation the PM3386 will send a PAUSE frame with a null Pause Timer value allowing quick PAUSE off signaling to downstream devices. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 47 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER 10.2.5 EGMAC Auto-Negotiation The EGMAC implements Clause 37 of the IEEE 802.3-1998 Standard, AutoNegotiation function, type 1000BASE-X. The Auto-Negotiation for 1000BASE-X function provides the means to exchange information between two devices that share a link segment allowing management the ability to configure both devices in such a way that takes maximum advantage of their capabilities. After a reset occurs the EGMAC senses whether or not Auto-Negotiation is enabled. If so the EGMAC will start Auto-Negotiation exactly following the state diagram as outlined in 802.3-1998 Clause 37. Base page Auto-Negotiation is therefore completely taken care of by the EGMAC. Above base page Auto-Negotiation, the EGMAC communicates between the host processor and an external MII physical device by means of a two wire interface. The EGMAC block produces the clock (MDC) and the general MII I/O pin MDIO. The host controls the EGMAC MII via the MII management registers. 10.2.6 EGMAC Address Filter Logic The EGMAC provides a rich set of address filtering options. The host microprocessor has complete programmable access to all filtering features. The EGMAC can perform 8 separate exact-match MAC/VID unicast filter operations. Each unicast filter will perform an exact match on either the DA or the SA, and an optional exact match on the VID. If enabled, each unicast filter channel can be programmed to indicate ACCEPT or DISCARD upon match. Each unicast filter channel can be enabled separately. The EGMAC also includes a 64-bin hash-based multicast filter. This hash-based filter utilizes 6-bits of the CRC-32 output taken over the MAC DA to provide the standard imperfect multicast filtering capability. The multicast filter output will be asserted only if the IEEE Group/Functional bit is set in the DA of the frame (Most significant bit of the least significant byte of the MAC DA). If enabled, the filter output will indicate ACCEPT only. If not enabled, it will indicate nothing. 10.3 Management Statistics (MSTAT) The MSTAT block is used to accumulate Ethernet specific counts used for supporting management agents such RMON, SNMP, and Etherlike interfaces. The MSTAT provides counter width support for compliance with 802.3-1998 PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 48 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER rollover requirements of 58 minutes. The MSTAT supports full system probing with counter snapshotting via shadow registers. Incorporated into the MSTAT block is a fully programmable interrupt array enabling per counter rollover monitoring with interrupt reporting. 10.4 POS-PHY Level 3 Physical Layer Interface 10.4.1 POS-PHY Level 3 General The PM3386 can connect to a single upper level device through a POS-PHY Level 3 Interface. The POS-PHY Level 3 interface is a 32-bits wide interface with a clock rate of 104 MHz. POS-PHY Level 3 was developed with the cooperation of the SATURN Development Group to cover all application bit rates up to and including 3.2 Gbit/s. The POS-PHY Level 3 specification defines the requirements for interoperation between devices such as the multi-PHY PM3386 and a single Link Layer device. Each channel within the PM3386 contains a 64k byte ingress and 16k byte egress POS-PHY latency FIFO. 10.4.2 POS-PHY Level 3 Ingress Physical Layer Interface (PL3IP) As a POS-PHY slave device, hence in the ingress or receive direction, the PM3386 outputs received packets to the upper layer device whenever data is available. The interface accepts a read clock (RFCLK) and read enable signal (RENB) when data is read from the ingress FIFO (using the rising edge of the RFCLK). The start of packet (RSOP) marks the first byte of received packet data on the RDAT[31:0] bus. The RPRTY signal reports parity on the RDAT[31:0] bus. Parity defaults to odd but may be programmed for even parity. The end of a packet is indicated by the REOP signal. The RERR signal is provided to indicate that an error in a received packet has occurred. The RVAL signal is used to indicate when RSOP, REOP, RERR, and RDAT[31:0] are valid. RSX indicates the start of transfer and marks the clock cycle where the in-band channel address is given on the RDAT[31:0] bus. In the event that the upper level device cannot accept data it can de-assert RENB. At this point the specific port’s POS-PHY interface ingress 64k byte FIFO will start to fill up. When the FIFO exceeds the programmed high water mark flow control threshold the ingress FIFO will assert an indication to the EGMAC to start PAUSE flow control. The ingress POS-PHY FIFO will continue to keep the flow control signal high until the number of entries in the FIFO have decreased to the programmed low water mark flow control threshold level. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 49 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER In the event that the link layer device does not re-assert RENB to continue the data flow the PM3386 will buffer the incoming frames from the line side interface until all the buffer facilities within the PM3386 are exhausted. At this time the PM3386 will no longer accept data from the line side. All data bits will be dropped at the line interface until resources within the PM3386 become available. At this time the PM3386 will re-sync to physical packet and continue reception. In the event that the PM3386 truncates a frame because of resource exhaustion the frame will be marked as erred by asserting the RERR bit on the last interface transaction for the packet transfer as specified by the PL3 bus protocol. The POS-PHY ingress FIFO will absorb in-flight frames when the PM3386 is placed into a PAUSE flow control state from the upper level device. The FIFO will accept a number of maximum size 9.6k byte frames without loss. The scheduling of packets through the ingress POS-PHY interface is controlled via a simple round robin approach that fairly switches between both Gigabit Ethernet channels. The POS-PHY bursts packets across the interface using programmable burst sizes. 10.4.3 POS-PHY Level 3 Egress Physical Layer Interface (PL3EP) The POS-PHY Level 3 compliant interface consists of a write clock (TFCLK), a write enable signal (TENB), the start of packet (TSOP) indication, the end of packet (TEOP) indication, erred packet (TERR) indication, and the parity bit (TPRTY). The PM3386 supports all three POS-PHY Level 3 egress status modes. The STPA signal reports the selected egress FIFO’s fill status. The PTPA signal shows the FIFO fill status for the polled channel. The DTPA[1:0] signal pins show the direct FIFO fill status on a per-channel basis. The TSX signal indicates when the in-band channel selection is given on the TDAT[7:0] pins. This is done at the beginning of each transfer sequence. If the in-band address does not equal 0 or 1 subsequent data transfers on the TENB bus will be dropped. The TMOD[1:0] signal is provided to indicate whether 1, 2, 3, or 4 bytes are valid on the final word transfer of the packet(TEOP is asserted). A packet may be aborted by asserting the TERR signal at the end of the packet. In the egress direction the PM3386 collects packets into the PM3386 egress FIFO and delays data transfer to the PM3386 EGMAC for transmission until the number of bytes gathered are equal to or greater than the PL3EP Channel Minimum Frame Size register or until end of packet (via TEOP) is signaled. Each packet must satisfy one of the two forwarding conditions prior to PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 50 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER transmission. This allows for programmable MAC underrun protection depending upon the application. 10.5 Microprocessor Interface The PM3386 uses a simple 16 bit multiplexed or non-multiplexed microprocessor interface that is commonly found on PMC-Sierra devices. The PM3386 supports complete accessibility to internal resources from the host microprocessor. This allows the host to read and write all host accessible registers and chip data structures. 10.6 JTAG Test Access Port Interface The JTAG Test Access Port block provides JTAG support for boundary scan. The standard JTAG EXTEST, SAMPLE, BYPASS, IDCODE and STCTEST instructions are supported. The PM3386 identification code is 033860CD hexadecimal.

Please refer to the operations section of this document for instructions concerning resetting this device using software. DIS_STRETCH: By default the internal digital reset is held asserted approximately 10ms after the de-assertion of the RSTB pin. To disable this delay the DIS_STRETCH bit can be set to logic 1. This will terminate the internal digital reset delay. By default this bit is disabled. Please refer to the operations section for further information.

Clearing this bit prevents any action based on the reception of PAUSE frames. Note that the PM3386 PAUSE counter will always reflect the PAUSE quanta as updated by incoming PAUSE frames.

This test feature may be used for board testing. In addition, the PM3386 also supports a standard IEEE 1149.1 five-signal JTAG boundary scan test port for use in board testing. All digital device inputs may be read and all digital device outputs may be forced via the JTAG test port.

The PM3386 shares a single ground VSS. Analog power AVDQ, AVDH and AVDL must be connected to properly decoupled independent +3.3V and +1.8V DC supplies respectively. The power-on sequence is as follows. Power to AVDQ and AVDH must be either applied simultaneously or that AVDQ be applied before AVDH. AVDL must come up before or simultaneously with AVDH. Power to VDDQ and VDDO must be either applied simultaneously or that VDDQ be applied before VDDO. VDDI must come up after or simultaneously with VDDO. VDDI and AVDL may have power supplied simultaneously. VDDO and AVDH may have power supplied simultaneously. 13.2 System Reset System reset for the PM3386 is accomplished via the RSTB pin. RSTB has a minimum reset pulse width of 1 ms. Prior to the de-assertion of RSTB the PMD_SEL pins must be in a stable state(strapped high or low) and all clocks for the device are required to be present for a minimum of 1ms. Internally when the RSTB signal is de-asserted the analog portion of the device will start to lock on to the various reference clocks. The digital portion of the device will be held in reset for 10 ms more by an internal timer. System status of analog training and progress can be viewed via the top level Device Status register. The system programmer may also elect to reset the PM3386 via software commands. This is accomplished by writing to the Reset Control register. The programmer is to write both the ARESETB and DRESETB to a 0. This asserts software reset. The programmer must pause no less than 1ms (there is no upper limit) then de-assert ARESETB by writing to the Reset Control register ARESETB bit with a 1. The programmer is to wait no less than 10ms (there is no upper limit) then de-assert DRESETB by writing to the Reset Control register DRESETB bit with a 1. As with assertion of the RSTB pin the programmer must PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 236 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER also insure that the PMD_SEL pins are in a stable state(strapped high or low) and all clocks for the device are present for a minimum of 1ms prior to initiating a software reset sequence. The internal digital reset delay may be overwritten using the DIS_STRETCH bit within the Reset Control register. This can be accomplished after a RSTB pin reset sequence and is not necessary when under software reset control. Note that the internal 10ms digital reset delay timer is only initiated after an appropriate RSTB pin reset sequence. Asserting software reset via ARESETB or DRESETB will not properly sequence the delay timer. 13.3 GMII vs. SERDES Configuration Each port within the PM3386 can be configured to use either the GMII or SERDES interfaces. The PMD_SEL0 and PMD_SEL1 pins are used for this purpose. Note that each port can be configured independently of the other. By tying the PMD_SELx pin to ground the device port will be placed in SERDES mode. By tying the PMD_SELx pin to 3.3v power the device port will be placed in GMII mode. 13.4 System Clocking 13.4.1 PHY-Link Frequency Selection The POS-PHY Level 3 bus (RFCLK and TFCLK) may be clocked from 60 to 104MHz. For two channel operation to allow for full bandwidth it is suggested that the bus be clocked at 104MHz. For single channel operation to allow for full bandwidth it is suggested that the bus be clocked at 75 MHz or greater. RFCLK and TFCLK go to separate clock domains within the PM3386. It is allowable for the system integrator to use the same or separate clock sources for both the RFCLK and TFCLK. RFCLK and TFCLK must be present during both GMII and SERDES mode of operation. 13.4.2 GMII Mode Clocking In GMII mode the PM3386 requires 3 separate clock inputs for proper operation. The RX_CLK0 and RX_CLK1 must be present for their respective PHY devices. The CLK125 must be present and valid from the clock generation source. The PM3386 will provide GTX_CLK0 and GTX_CLK1 that is properly aligned to the TXD0[7:0] and TXD1[7:0] data busses respectively. GTX_CLK0 and GTX_CLK1 PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 237 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER are derived from the CLK125 input. Please see 13.6 for an example of this configuration. 13.4.3 SERDES Mode Clocking During SERDES mode the PM3386 requires only one clock source. CLK125 must be supplied from a reliable source. Note that it is possible to have one channel in SERDES mode and one channel in GMII mode. In this case the PM3386 shares the CLK125 input for both channels. The GMII mode port must still receive the RX_CLKx for that specific channel. 13.5 Interfacing to ODL The PM3386 interfaces to many common Fiber Optic Transceivers by way of a high speed PECL interface. The PECL transmit TXD+/- and the receive RXD+/signals require AC coupling. Figure 4 PM3386 SERDES to Fiber-Optic Transmitter PM3386 AVDH VBIASODL 49.9 Ω 50 Ω TX - PECL Output C1 50 Ω 49.9 Ω TX - PECL Input TX + C2 TX + PM3386 Fiber-Optic Transmitter Fiber-Optic Transmitter AVDH 50 Ω TX - PECL Output C3 50 Ω 100 Ω C4 TX + TX - PECL Input TX + Figure 4 represents a typical application showing the transmit datapath termination. Note that the characteristic impedance for the termination is 50 Ω single ended or 100 Ω differential. Values for C1, C2, C3, and C4 are recommended to be 100nF. Please note that many of the transceivers on the market may contain the needed termination resistors and capacitors.

Please note the internal 50 Ω single ended termination within the PM3386 receive PECL cells. Please follow the manufactures recommended requirements when interfacing the Fiber-Optic Receiver to the PM3386. Differing Fiber-Optic Receivers require differing values for the R1 and R2 termination resistors. RXSD0 and RXSD1 may be used as the input signal detect for transceivers that support this feature. In general component placement should be carefully considered. The differential impedance of the line should be kept to 100 Ω. This requires good separation of the board lines to provide for proper impedance matching and reduction of signal reflection. Please refer to the AC timing specification section of this document for clock and data signal specifications. 13.6 GMII Interfacing The PM3386 may receive the 125MHz CLK125 reference clock input from either a stand alone high precision clock oscillator or via the output from a common 802.3 compliant Gigabit Ethernet transceiver. In either case the PM3386 uses the 125MHz CLK125 input to produce the GTX_CLK0 and GTX_CLK1 outputs to the Gigabit Ethernet transceiver. GTX_CLKx is aligned with the TXD0[7:0] and TXD1[7:0] output pins. In the case of using the PM3386 with one channel in SERDES mode and one channel in GMII mode the timing requirements for the CLK125 must still be achieved.

The TBI passes encoded 8B/10B data to and from the PM3386 over the same lines as used for GMII. A pin relationship can be made by referencing the below table. Table 31 GMII to TBI Pin Mapping Receive Transmit GMII TBI GMII TBI TX_ER TX[9] RX_ER RX[9] TX_EN TX[8] RX_DV RX[8] TXD[7] TX[7] RXD[7] RX[7] TXD[6] TX[6] RXD[6] RX[6] TXD[5] TX[5] RXD[5] RX[5] TXD[4] TX[4] RXD[4] RX[4] TXD[3] TX[3] RXD[3] RX[3] TXD[2] TX[2] RXD[2] RX[2] TXD[1] TX[1] RXD[1] RX[1] TXD[0] TX[0] RXD[0] RX[0] GTX_CLK GTX_CLK RX_CLK RX_CLK The following process is required to initialize the PM3386 into TBI mode. It is assumed that the given PM3386 port has it’s PMD_SELx pin pulled high for GMII mode. This sequence should be executed immediately after power-up or a hardware reset. 1. Write bit 0 (MIIM) of register 0x300 (hex) or 0x400 (hex) for ports 0 and 1 respectfully to a 0. 2. Write bit 6 (SDSEL) of register 0x703 (hex) or 0x713 (hex) for ports 0 and 1 respectfully to a 1. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 240 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER 3. Write bit 11 (RXSD) and bit 15 (FORCE) of register 0x704 (hex) or 0x714 (hex) for ports 0 and 1 respectfully to a 1. 13.8 Enabling and Disabling Data Flows Data flows within the PM3386 can be halted or enabled via programmable control. The RXEN0 and TXEN0 bits within each EGMAC GMCC1 register along with the TPAUSE bit in the EGMAC Transmit Control register enables and disables the receive and transmit data flows respectively. 13.8.1 Enabling and Disabling Ingress Data Flow When the RXEN0 bit is low, the given channel will cease data transfer for the receive or ingress direction of the deice. If the device is in the middle of receiving a frame, the frame reception will complete. All further frames on the line side interface will be dropped. All frames that have been received prior to halting will be allowed to be sent to the link via the ingress PL3 bus. By default the PM3386 comes out of reset with the RXEN0 bit low (i.e. traffic halted). To enable the data flow set the RXEN0 bit for the given channel high. 13.8.2 Enabling and Disabling Egress Data Flow The TXEN0 and TPAUSE bits control data flow in the egress or transmit direction. Upon reset the TXEN0 and TPAUSE bits will be low. To enable data flow after reset the TXEN0 bit must be asserted high. To enable or disable data transfer in cases other than reset the TPAUSE bit must be used. To disable egress or transmit data set the TPAUSE bit to high. If the PM3386 is in the middle of sending a frame, that frame will be finished without error. With the frame transmitted the PM3386 will cease to transmit any more frames. If the link devices continues to write data to the PM3386, that data will be buffered until all egress buffer resources have been used. When the egress buffer resources have been used up, flow control signals will be presented to the link device via the DTPA, STPA, and PTPA signals. To re-enable data flow set the TPAUSE bit low. 13.9 Register Access Procedures The PM3386 register map allows for direct access to all device register via simple microprocessor reads and writes. Most register do not have side effects when read or written to other that that which is specified within the register description. There are some register within the device that require specific access procedures to allow for proper operation. These special procedures will be noted below and within the corresponding register descriptions. Upon chip PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 241 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER initialization it is recommended that the differing configuration register be written to the appropriate values for the application before traffic transfer is enabled. 13.9.1 PL3IP Register Access Procedure The differing PL3IP configuration registers (0x104, 0x105, 0x120, 0x121, 0x122, 0x140, 0x141, 0x142) may be written to at any time but will only be updated when the Channel Enable (IP_CR[7]) bit is set to zero. 13.9.2 PL3EP Register Access Procedure The differing PL3EP configuration register (0x220, 0x221, 0x240, 0x241) may be written to at any time but will only be updated when the Channel 0 Update (EP_CR[2]) or Channel 1 Update Register(EP_CR[3]) bits are set to zero respectively. 13.9.3 EGMAC Register Access Procedure The differing EGMAC configuration registers (0x300, 0x301, 0x302, 0x303, 0x304,0x305, 0x400, 0x401, 0x402, 0x403, 0x404, 0x405) require an EGMAC software reset to enable the state machines within the EGMAC to obtain the new configuration value. The software reset is done with the SRST bit in the EGMAC GMACC0 Config Register High Word Register(0x301, 0x401). The EGMAC address filter configuration registers can be written to at any time but will only be updated when the Update bit is set within the EGMAC Address Filter Control 3 Register(0x360, 0x460).

However, Ethernet data is always transmitted and received via the EGMAC line side in the following format. Bits are transmitted and received from the top to bottom and from left to right. For example, for the destination address (DA[47:0]), bit DA[0] is transmitted first and bit DA[47] is transmitted last.

Below is the format for big endian data transfer. Note that both the system side POS-PHY interface and the ingress or egress FIFOs contain the same data mapping.

As noted in the SERDES Port Configuration register, by setting bits TXSEL[1:0] to 11 the PM3386 will be enabled in a line side loop back configuration. Note that to use this feature the external reference clock (CLK125) and the recovered data clock must be externally locked to the same frequency source. The use of different reference frequencies will ultimately cause the internal SERDES FIFO to underflow or overflow. Upon detection of the underflow or overflow the SERDES FIFO will automatically re-center itself, however, the re-centering action will cause a discontinuity in the repeated data stream. When the reference clock (CLK125) and the receive data stream are derived for the same frequency source (synchronous operation) and meet all other SERDES input timing requirements, and their peak relative jitter is less than +/-8ns, no FIFO slips should occur. By setting bit RXSEL to 1 in the PM3386 SERDES Port Configuration register the device will be enabled into a system side loop back mode. This feature will exercise the entire datapath through the PM3386. 13.12 GMII Loopback The PM3386 can perform system side loop back using the differing sections of the EGMAC to complete the loop back path. As noted in the EGMAC GMACC0 PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 244 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER register by setting either bits L32B or L10B the EGMAC will loop back the egress data coming from the PL3 bus to the ingress data going out of the PM3386 via the PL3 bus. The L32B bit causes the 32 bit data bus prior to the GMII or 8B/10B encoder/decoder to be looped back. The L10B bit causes the 10 bit data in the GMII or 8B10B encoder/decoder to be looped back. If both L32B and L10B bits are set the 32 bit path will be used. From the system level perspective there is no difference between the L10B and L32B looped back data 13.13 IFG Manipulation The PM3386 can receive frames continuously at the normal receive interval of equal to or greater than 96 ns. The normal receive interval is specified as the time between the last byte of the previous frames CRC and the sampling of the Start of Frame Delimiter (SFD) as shown in Figure 6 Figure 6 GMII minimum receive interval Receive Interval RX_DV DE-ASSERTION rx125 rx_dv SFD PREAMBLE 55 55 55 rxd[7:0] D5 01 02 For transmit or egress traffic the PM3386 will insert the appropriate IFG of 96ns by default. The transmit IFG is also programmable allowing frame traffic shaping on back-to-back frames. The IPGT[5:0] field in the EGMAC GMACC2 register defines the programmable back-to-back IFG between frames. This field is programmed to the number of octets of IFG desired. A setting of 12 decimal represents the minimum IFG of 96 ns. Note that this register is expressed in byte times. 13.14 Frame Length Support The PM3386 supports jumbo frames up to 9.6k bytes. The EGMAC Max Receive Frame Length register controls the maximum size of the ingress frame. If the frame is greater than the programmed size the frame will be treated as a long or jabber frame. The minimum frame size on the ingress channel is 64 bytes. The EGMAC Transmit Max Frame Length register controls the PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 245 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER maximum size of the egress frame. If the frame is greater than the programmed size the frame will be treated as long and thus truncated. The minimum frame size on the egress channel is 64 bytes. The EGMAC Receive FIFO Forwarding Threshold register sets the forwarding threshold used for ingress frame gathering and error reporting. Frames are passed from the EGMAC to the PL3 ingress FIFO if an end of frame indication has been received by the EGMAC or the number of bytes received by the EGMAC is greater than the EGMAC Receive FIFO Forwarding Threshold register. This mechanism provides for two different frame error handling capabilities. First if the forwarding threshold is set higher than the received frame size the EGMAC will drop and not forward the erred frame. Second if the forwarding threshold is set lower than the received frame size the EGMAC will immediately start passing the incoming frame as soon as the threshold is reached. When the EGMAC determines the end of frame and an error is detected the EGMAC marks the frame as erred and the PM3386 will assert RERR on the data transfer of the packet on the PL3 bus. The PL3EP Channel Minimum Frame Size register sets the forwarding threshold used for egress frame gathering. Packets passed to the PM3386 on the PL3 bus will be gathered in the egress FIFO until an end of packet indication or until the number bytes transferred to the PM3386 are greater than or equal to the PL3EP Channel Minimum Frame Size register. This allows a slow link device to ensure that an entire packet is prepared within the PM3386 before the transmitting the packet on the line. For faster link devices the threshold can be set to the minimum 64 bytes to remove system latency penalties. 13.15 Transmit Padding and CRC Generation The PM3386 can pad transmit or egress frames to minimum legal frame lengths and append a proper FCS to the frame prior to transmit. This is accomplished only if the PADEN bit is set in the EGMAC GMACC1 register. Note that in this mode that all frames less than the minimum frame size of 64 bytes will be considered to not have a valid CRC and will have a FCS appended after padding. The PM3386 can append a proper FCS to each and every frame prior to transmission if the CRCEN bit within the EGMAC GMACC1 register is set. The resulting minimum egress frames transmitted by the PM3386 can be understood through the following table.

There are five registers that are used to read and write to the external gigabit PHY’s. These are EGMAC MCMD, EGMAC MADR, EGMAC MWTD, EGMAC MRDD and EGMAC MIND. The bit definitions and details of these registers are defined in the Normal Mode Register Description. The access to the PHY’s are separated into Read Access and Write Access. These Accesses are described below: 13.16.1 MII Read Access 1) Write the PHY Address and PHY Register Address to the EGMAC MADR register. 2) Write the RSTAT bit (bit – 0) in the EGMAC MCDM register with a 1. This will start the read process and set the MBSY bit in the EGMAC MIND register. 3) Wait for or poll the MBSY bit in the EGMAC MIND register until the MBSY bit is low. 4) Once the MBSY bit is low then the data in EGMAC MRDD is valid. Read the EGMAC MRDD register for the data. 5) Write the RSTAT bit (bit – 0) in the EGMAC MCDM register with a 0. 13.16.2 MII Write Access 1) Write the PHY Address and PHY Register Address to the EGMAC MADR register. 2) Write the data to be written to the EGMAC MWTD register. The MBSY bit in the EGMAC MIND register will be asserted until the write access is complete. 13.17 Auto-Negotiation The PM3386 implements Clause 37 of IEEE 802.3-1998 Auto-Negotiation function type 1000BASE-X. The Auto Negotiation for the 1000BASE-X function provides the means to exchange information between two devices that share a link segment allowing management the ability to configure both devices in such a way that takes maximum advantage of their capabilities. Auto-Negotiation is performed using special 10-bit ordered sets defined within Clause 36 of the IEEE PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 248 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER 802.3 Standard. The EGMAC module takes care of all Auto-Negotiation functions inside of the PM3386. After reset the PM3386 senses AutoNegotiation Enable bit (ANEN) from the EGMAC Auto-Negotiation Control register to determine whether or not the Auto-Negotiation is enabled. If not enabled, the PM3386 transmits frames normally interspersed with idles. If, however, the ANEN control signal is active, the PM3386 starts the AutoNegotiation State Machine. The Auto-Negotiation State Machine follows the state diagram exactly as outlined in 802.3-1998 Clause 37. The configuration word to be transmitted is set to 0x0000h. The “all zero” configuration word is transmitted to the Link Partner as a /C/ (Configuration) ordered set to the link partner for a duration of 10ms as governed by the Link Timer in the EGMAC module. After 10ms is complete, the PM3386 transmits /C/ ordered sets containing the EGMAC Base Page register, with ACK not set. This is done continuously until the PM3386 detects Ability Match Received (ABMRX) which indicates that three consecutive matching /C/ ordered sets have been received ignoring the ACK bit. The PM3386 then continuously transmits /C/ ordered sets containing the EGMAC Base Page register, with ACK set. This is done until the PM3386 detects Acknowledge Match Received (ACMRX) which indicates that three consecutive matching /C/ ordered sets have been received with the ACK bit set. The PM3386 then determines if there has been consistency in the /C/ ordered sets received. If so, it proceeds to start the Link Timer once more. When the Link Timer finishes and if either device does not advertise an ability to exchange Next Pages, the PM3386 transmits idles /I/. The Link Timer is then stared once more. When the Link Timer is done, the PM3386 verifies that IDMRX is active (receiving idles), which verifies that the link partner has gone through its AutoNegotiation process and is ready to start sending and receiving frame data. IDMRX active prompts the Auto-Negotiation State Machine to transition into its final state and to assert the Auto-Negotiation Complete (ANCPLT) signal. This informs the system that packet data can be sent across the link. The Auto-Negotiation state machine will stay in this final state until any of these following events occur: 1. The Auto-Negotiation is restarted by the EGMAC Management register (RSTAN) bit being asserted. 2. The EGMAC or PM3386 is reset. 3. The synchronization state machine in the EGMAC flags a loss of code synchronicity.

ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER The Link Partner remotely re-initiates the Auto-Negotiation process by sending /C/ order sets containing the “all zero” configuration codeword. When any of the above events occur, the EGMAC Auto-Negotiation state machine will transition from its final state to its starting state and the process will start from the beginning. 13.17.1 Monitoring Auto-negotiation To monitor Auto-negotiation the host reads the EGMAC ANSTT register for status and can also read the EGMAC ANLPA register to get information on the link partner. The register and bit definitions for these registers are defined in the Normal Mode Register Description section. 13.17.2 Modifying Auto-negotiation To modify Auto-negotiation the host reads and writes the EGMAC ANNPG/ANADV register for Advertisement on this device. The register and bit definitions for these registers are defined in the Normal Mode Register Description section. 13.17.3 Control of Auto-negotiation To control Auto-negotiation the host reads and writes the EGMAC ANCTL register for control of enabling/disabling or re-starting auto-negotiation on this device. The other control is the AUTOS bit (bit – 8) in the EGMAC GPCSC register, when asserted this bit will cause the MAC to auto sense if the Link Partner is in Link Bypass or Auto-neg is disabled. The register and bit definitions for these registers are defined in the Normal Mode Register Description section. 13.18 TX_ER Assertion Criteria TX_ER on the PM3386 line side will be asserted if any of the following conditions are present: 1. If the link asserts TX_ERR on the last word of a PL3 egress data transfer. 2. If parity checking is enabled in the PL3EP Configuration register and invalid parity is determined on any PL3 egress data transfer word. 3. If parity checking is enabled in the PL3EP Configuration register and invalid parity is determined on a valid TSX address cycle.

If the egress frame to be transmitted is considered short, long, without a valid CRC, or any type of internal transmit MAC error. 13.19 Frame Filtering The PM3386 has simple programmable options to filter or forward ingress frames to the upstream link device. The PM3386 EGMAC Receive Address Filtering Logic consists of eight exact-match MAC/VID filters, one 64-bin hash based multicast filter and four address filtering control registers that control the state of the forwarding for each filter. Each exact match filter includes one 48-bit MAC Address register and one 12-bit VID register that can be programmed through the microprocessor interface to the appropriate values. The filter logic is controlled by the four EGMAC Address Filter Control registers. The host microprocessor has complete programmable access to all filtering features. 13.19.1 Group Multicast Address Filtering In parallel with the exact address match, the PM3386 performs multicast filter lookups. Within the PM3386 there resides a 64-bin hash based multicast filter per channel consisting of one 64-bit mask register that is programmable from the Microprocessor interface (EGMAC Multicast Hash register). This register is used in conjunction with a 6-bit value which is derived from bits [28:23] of the 32bit CRC computed over the Destination Address. This 6-bit value is used to index into the 64-bit mask register. The 64-bit mask register is used to determine if a multicast address that hashes to a given bin will be accepted for forwarding The 64-bin hash based multicast filtering is enabled by the MHASH_EN bit in the EGMAC Address Control 2 register. If the MHASH_EN bit is 0 then there is no hash based multicast filtering, however if MHASH_EN is 1 then hash based multicast filtering is enabled. The multicast hash filter operation operates only on multicast-type frames: those with the IEEE Group/Functional bit set in the DA of the frame (most significant bit of the least significant byte of the MAC DA). The 48-bit destination address of the received frame is passed through the standard 802.3 CRC function in the same order in which the destination address octets are received. Making reference to the 802.3 specification, section 3.2.8 Frame Check Sequence field, the CRC function generating polynomial and function is: G(x) = x32+x26+x23+x22+x16+x12+x11+x10+x8+x7+x5+x4+x2+x1+1 1. The first 32-bits of the frame (which is the first 32-bits of the destination address received) are complemented. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 251 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER 2. The 48 bits of the destination address are then considered to be the coefficients of a polynomial M(x) of degree 47 32 3. M(x) is multiplied by x and divided by G(x), producing a remainder R(x) of degree <= 31. 4. The coefficients of R(x) are considered to be a 32-bit sequence. Bits [28:23] of the resultant 32-bit CRC remainder (call this crc_rem[28:23]) are used as the index into the MHASH[63:0] register. The result of the Group Multicast address filter is logically represented by the variable MHASH_ACCEPT: MHASH_ACCEPT = (MHASH_EN == 1) & (MHASH[ crc_rem[28:23] ] ==1); 13.19.2 Exact Match Filter Program Options Each of the eight exact match filters on each EGMAC has four bits of associated configuration. These are found in the Address Filter Control 0 and Address Filter Control 1 registers: 1. ADRFILT_CTRLx[0] enables the exact match operation. If this bit is a logic 0 then the EXACT_MATCH operation returns a logic 0. 2. ADRFILT_CTRLx[1] enables the match function to also compare the VLAN Tag VID[11:0] field of the receive frame if the two bytes following the receive frame source address are equal to the VLAN Tag ID register 3. ADRFILT_CTRLx[2] selects whether the source address or destination address of the received frame is used as the address for matching. 4. ADRFILT_CTLRx[3] is a configuration bit that determines whether an exact match will affect the variable ACCEPT or DISCARD. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 252 PM3386 RELEASED DATASHEET PMC-1991129 13.19.3 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER Exact Match Filter Operation The exact match filter operation is a two step process. The first step is to determine whether the address match criteria is logically true: EXACT_MATCH is logic 1 if the exact match filter is enabled and the selected frame address (and optional VID field of a VLAN tagged frame) are equal; otherwise, EXACT_MATCH is logic 0. The second step is to set the EXACT_MATCH_ACCEPT or EXACT_MATCH_DISCARD variable for the given (one of eight) exact match filters based on the setting of ADRFILT_CTRLx[3] register bit: EXACT_MATCH_ACCEPT = EXACT_MATCH & (ADRFILT_CTRLx[3] == 1); EXACT_MATCH_DISCARD = EXACT_MATCH & (ADRFILT_CTRLx[3] == 0); 13.19.4 Address Filter ACCEPT / DISCARD Evaluation The final result of the address filter function is a single filter versus forward decision. This again is a two step process. First the result of the Group Multicast Address filter is combined with the result of the eight possible exact match filter operations to determine a final filter versus forward decision. Let EXACT_MATCH_ACCEPT[7:0] and EXACT_MATCH_DISCARD[7:0] represent the ACCEPT and DISCARD variables for the eight independent exact match filters respectively. The final combined value of ACCEPT and DISCARD for all address filters is logically: ACCEPT = (EXACT_MATCH_ACCEPT[7:0] != 0) | MHASH_ACCEPT; DISCARD = (EXACT_MATCH_DISCARD[7:0] != 0); Secondly the address filter logic can be configured so that a frame has a higher priority for being forwarded or filtered: this decision is based on the configuration bit PMODE in the Address Filter Control 2 register.

A frame will be filtered only if ACCEPT is true and DISCARD is false. This is shown in the following table. It should be noted that if all filters are disabled, then all frames are filtered.

Program the EGMAC Multicast Hash register with the desired bit mask and enable by programming the EGMAC Address Filter Control 2 register. 2. Enable the programmed values to take effect by writing to the UPDATE bit within the EGMAC Address Filter Control 3 register. Upon a write to this register the EGMAC updates all of the filter information for the device upon the end of the reception of the current frame. If not currently receiving frames the filter logic will be updated immediately. When the update has happened the UPDATE bit will be self-cleared by the EGMAC. 13.20 PAUSE Flow Control The PM3386 allows 802.3 PAUSE frames to be transmitted out the egress MAC port based on three separate PAUSE frame catalysts aside from client based PAUSE frame injection. These conditions are discussed further in this section but first a general description of the PM3386 PAUSE frame generation is desired. The Transmit PAUSE Control Frame logic responds to a Transmit PAUSE Control Request caused from either: 1. Internal FIFO Flow Control. 2. External side-band PAUSE Request. 3. External host based PAUSE Request. In each case the PM3386 responds by initiating a Transmit PAUSE Frame State. The logic, if need be, waits for the current frame transmission to end before attempting to send a PAUSE control frame. The PAUSE control frame is formatted as follows: PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 255 PM3386 RELEASED DATASHEET PMC-1991129 Table 37 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER - PAUSE Control Frame Format Octets Frame Field Source of Information 7 Octets Preamble Auto-generated 1 Octet SFD Auto-generated 6 Octets Destination Address Auto-generated (01-80-c2-00-00-01) 6 Octets Source Address EGMAC Station Address register. User defined 2 Octets Length/Type Field Auto-generated (88-08) 2 Octets Opcode Field Auto-generated (00-01) 2 Octets PAUSETimer Field EGMAC PAUSE Timer register: By default FF-FF 42 Octets PAD Auto-generated 4 Octets FCS Auto-generated Note that DA[7:0] = 01, DA[15:8] = 80…etc. The PAUSE frame is stitched together using register based information and a series of auto-generated fields. As long as the PM3386 is in the Transmit PAUSE Frame State the EGMAC will continually send a PAUSE control frame each time the internal EGMAC PAUSE Timer Interval register counts down to zero. In this fashion the egress data-pipe will not be blocked for normal egress data traffic. The EGMAC PAUSE Timer and EGMAC PAUSE Timer Interval registers are both programmable. By default the EGMAC PAUSE Timer register defaults to 0xFFFF and the EGMAC PAUSE Timer Interval register defaults to 0x7F67. Both are representative of the number of PAUSE Quanta used in the system. Note that PAUSE Quanta is defined as 512 bits. The EGMAC PAUSE Timer Interval will reload to the programmed state when it reaches zero. It is the responsibility of the PAUSE catalyst to hold the input to the EGMAC until normal ingress traffic can be resumed. When the catalyst removes the request for PAUSE the EGMAC will send out a PAUSE Control frame with the PAUSE timer value of zero. Aside from the POS-PHY Level 3 client sending PAUSE Control frames there are three different PAUSE frame catalysts. These are discussed below. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 256 PM3386 RELEASED DATASHEET PMC-1991129 13.20.1 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER Internal FIFO Flow Control The ingress FIFO logic is programmable via the PL3IP Channel High Watermark register to the FIFO fill level that will trigger a PAUSE flow control signal. When the POS-PHY ingress FIFO exceeds this level the PL3IP module asserts an internal signal to the EGMAC requesting PAUSE flow control. The EGMAC can be programmed to accept POS-PHY FIFO PAUSE flow control requests for egress traffic if the FCTX bit is set in the EGMAC GMACC1 register. When enabled and the internal signal is asserted the EGMAC will commence sending 802.3 PAUSE frames. The PL3IP logic will continue to hold the pause request signal to the EGMAC until the separate PL3IP Channel Low Watermark register threshold has been achieved. At this time the pause request signal will be de-asserted informing the EGMAC to cease PAUSE frame flow control by sending a PAUSE Control frame with the PAUSE timer value of zero. 13.20.2 External Side-Band PAUSE Request The PAUSE0 and PAUSE1 signals are sideband PAUSE request signals synchronous to RFCLK. When the IP_CR[6] PAUSE Mode Selection bit in the PL3IP Configuration Register is set to zero the PAUSE0 and PAUSE1 signals, when asserted, will activate the same PAUSE mechanism in the EGMAC that the internal FIFO fill levels would have accomplish. These signals are useful when lack of resources in the upper level device becomes critical and the upper level device would like to send PAUSE frames on the egress data-path while continuing to receive frame data on the ingress datapath without blockage. These signals are asserted and held as long as PAUSE frames are required to be sent out the egress interface. When normal frame reception is desired the PAUSE0 or PAUSE1 signals can be de-asserted. Upon de-assertion the given channel will transmit a PAUSE Control frame with the PAUSE timer value of zero. When the IP_CR[6] PAUSE Mode Selection bit in the PL3IP Configuration Register is set to one the PAUSE0 and PAUSE1 signals, when asserted, will allow the given programmed data burst on the corresponding channel to complete and then halt data traffic on that channel until the PAUSE0 or PAUSE1 for the corresponding channel is de-asserted. Uner this mode the PAUSE Control frame generation defaults to Internal FIFO Flow Control as described above. This mode allows the upper layer POS-PHY Level 3 device to bypass RENB (always assert RENB). This removes a possible head-of-line block problem that might be inherint in the system design. In this mode PAUSE0 and PAUSE1 become the individule RENB signals for the PM3386. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 257 PM3386 RELEASED DATASHEET PMC-1991129 13.20.3 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER External Host Based PAUSE Request The PM3386 allows and external microprocessor to initiate transmission of PAUSE frames by programming the internal HOSTPAUSE bit in the EGMAC Control register. When the HOSTPAUSE bit is set the EGMAC is placed in a Transmit PAUSE Frame State. When cleared no PAUSE frames will be transmitted. Again when transitioning from a Transmit PAUSE Frame State to no PAUSE a PAUSE Control frame will be sent with a PAUSE timer value of zero. 13.20.4 Reception of 802.3 PAUSE frames. The PM3386 can be programmed to handle ingress PAUSE control frames in the manner as outlined below. This programming is done via the PASS_CTRL bit in the EGMAC Control register and the FCRX bit in the EGMAC GMACC1 register. The PASS_CTRL bit programs whether or not control frames are passed to the upper layer device. The FCRX bit programs whether or not the PM3386 follows 802.3 PAUSE flow control. Table 38 PASS_CTRL PAUSE Frame Programmable Control FCRX PM3386 Action 0 0 PAUSE Frames are ignored and dropped at the PM3386 level. 0 1 PAUSE Frames are executed but are no passed to the upper layer. 1 0 PAUSE Frames are ignored and forwarded to the upper layer device. 1 1 PAUSE Frames are executed and forwarded to the upper layer device. Please note as per 802.3-1998 that if the PM3386 is currently executing reception of a PAUSE frame and is currently blocking the egress data-path from transmission of normal data traffic that it is still possible to send PAUSE control frames by following the prescribed flow control methods in 13.20. 13.21 Ingress POS-PHY Buffer Thresholds The PM3386 contains 64k bytes per channel ingress buffers. Each buffer is organized in standard FIFO format. The FIFO’s are filled with data from the PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 258 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER ingress EGMAC interface and are drained on the PL3 side by the link device. Each FIFO has programmable threshold to provide for system ingress flow control and hysteresis. Figure 7 represents the PM3386 ingress FIFO structure as a simple bucket for easier explanation. The pm3386 will fill the FIFO with data coming in from the EGMAC line side interface. When the number of bytes in the FIFO are greater than the programmed threshold in the PL3IP PL3IP High Watermark register a signal is sent to the EGMAC from the FIFO to start flow control. If enabled the EGMAC will start sending PAUSE frames out on the media. When the ingress FIFO is drained past the threshold programmed in the PL3IP PL3IP Low Watermark register the signal to the EGMAC telling it to flow control will become de-asserted. The EGMAC will cease to send PAUSE frames with the transmission of a final PAUSE Control frame with the PAUSE timer value set to zero. If the FIFO fills to the programmable level as contained within the PL3IP Equalization Threshold Limit register the PM3386, if enabled, will start monitoring for channel starvation. This feature allows the PM3386 to compensate for lack luster channel performance caused by a slow link draining devices or radically unmatched data sizes between channels. Channel equalization allows for a more fair data flow across the PL3 bus promoting greater bandwidth optimization. Once the Equalization Threshold Limit is reached the PM3386 monitors the difference in bytes between the two internal ingress FIFOs. If this byte difference becomes greater than or equal to the PL3IP Equalization Difference Limit register the PM3386 will initiate channel equalization. During channel equalization all know rules of burst size and packet handling will still be observed but the arbitration will take into account the differential fill levels of the FIFOs favoring the FIFO that has the fullest level. This mode of operation is transparent to the link device. All PL3 bus protocols are still observed.

Each buffer is organized in standard FIFO format. The FIFO’s are filled with data from the egress PL3 interface and are drained at the internal chip side by the EGMAC. Each FIFO has programmable thresholds to provide frame gathering and PL3 bus flow control. Figure 8 represents the PM3386 egress FIFO structure as a simple bucket for easier explanation. The PL3EP Channel Minimum Frame Size register is used to promote the gathering mechanism of the egress FIFO. As the FIFO is filling with a packet, the FIFO will not start draining packet data until either the fill level is greater than or equal to the threshold programmed in the PL3EP Channel Minimum Frame Size register or until an End of Packet (via TEOP) has been written to the FIFO. This allows the down stream link device to deposit the entire packet into the EGRESS channel prior to transmission by the PM3386 on to the wire. The programmer may prefer, depending on the application, to set the gathering threshold low in order to promote lower system latencies. In this case of a small gather threshold programmed in the PL3EP Channel Minimum Frame Size register the link device must keep the egress PL3 FIFO full in order to not under-run the PM3386 transmission datapath. In the event that an under-run condition does happen the PM3386 will recover gracefully incrementing all appropriate counters and marking the outgoing frame as being in error. When the PM3386 egress FIFO PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 260 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER receives an EOP from the link device the given frame will be sent regardless of the programmed gathering threshold. The next frame after the EOP will have to satisfy either the Channel Minimum Frame Size or EOP requirements prior to transmit. It is therefore possible to set the gathering threshold to only send packets when all of the per packet contents they have been gathered into the egress FIFO. This ensures non under-run conditions caused by link devices that may be slower to insert data into the egress FIFO via the PL3 interface. The PM3386 provides a rich set of egress flow control signals generated toward the link device. These signals include DTPA, STPA, and PTPA. In each case the flow control signals all originate from a single source. As the egress FIFO fills the number of bytes left in the FIFO is monitored and compared to the threshold set in the PL3EP Channel FIFO Reserve register. When the fill limit meets or exceeds the programmed fill limit the PM3386 de-asserts the status signals DTPA, STPA, and PTPA. This mechanism allows the device user to select at which point they would like to start the flow control measures. If the link device ignores the TPA signals and attempts to overflow the egress FIFO the PM3386 will truncate the offending packet. The PM3386 will wait until a small amount of egress FIFO has been recovered then resume accepting data from the link device.

If desired the PM3386 can be programmed to use even parity. Please see the PL3IP Configuration and PL3EP Configuration registers for selection options. 13.24 POS-PHY Frame Burst Sizes The ingress datapath of the PM3386 has a programmable PHY-to-Link byte burst capability. The PM3386 can be programmed to send ingress data transfers in multiple byte bursts as programmed by the PL3IP Channel Packet Burst Mask registers within the PL3IP block. 13.25 Interrupt Handling The PM3386 signals the host processor via the use of the INTB active low signal. When INTB is asserted the host processor can interrogate the PM3386 for the source of the interrupt by reading the Interrupt Status register. The resulting information will provide the programmer with the block from which the interrupt originated. To clear the interrupt the host processor reads the block interrupt as decoded by Table 13. A read from this block register will clear the block level interrupt. Note that there may be more than one block level interrupt. To clear the device level interrupt all block level interrupts must be cleared or masked off. 13.26 JTAG Support The PM3386 supports the IEEE Boundary Scan Specification as described in the IEEE 1149.1 standards. The Test Access Port (TAP) consists of the five standard pins, TRSTB, TCK, TMS, TDI and TDO used to control the TAP controller and the boundary scan registers. The TRSTB input is the active-low reset signal used to reset the TAP controller. TCK is the test clock used to sample data on input, TDI and to output data on output, TDO. The TMS input is used to direct the TAP controller through its states. The basic boundary scan architecture is shown below.

The instruction register with instruction decode block is used to select the test to be executed and/or the register to be accessed. The bypass register offers a singlebit delay from primary input, TDI to primary output, TDO. The device identification register contains the device identification code. The boundary scan register allows testing of board inter-connectivity. The boundary scan register consists of a shift register place in series with device inputs and outputs.

In addition, patterns can be shifted in on primary input, TDI and forced onto all digital outputs. 13.26.1 TAP Controller The TAP controller is a synchronous finite state machine clocked by the rising edge of primary input, TCK. All state transitions are controlled using primary input, TMS. The finite state machine is described below.

The state is entered asynchronously by asserting input, TRSTB. The state is entered synchronously regardless of the current TAP controller state by forcing input, TMS high for 5 TCK clock cycles. While in this state, the instruction register is set to the IDCODE instruction. Run-Test-Idle The run test/idle state is used to execute tests. Capture-DR The capture data register state is used to load parallel data into the test data registers selected by the current instruction. If the selected register does not allow parallel loads or no loading is required by the current instruction, the test register maintains its value. Loading occurs on the rising edge of TCK. Shift-DR The shift data register state is used to shift the selected test data registers by one stage. Shifting is from MSB to LSB and occurs on the rising edge of TCK. Update-DR The update data register state is used to load a test register's parallel output latch. In general, the output latches are used to control the device. For example, for the EXTEST instruction, the boundary scan test register's parallel output latches are used to control the device's outputs. The parallel output latches are updated on the falling edge of TCK. Capture-IR The capture instruction register state is used to load the instruction register with a fixed instruction. The load occurs on the rising edge of TCK. Shift-IR The shift instruction register state is used to shift both the instruction register and the selected test data registers by one stage. Shifting is from MSB to LSB and occurs on the rising edge of TCK. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 266 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER Update-IR The update instruction register state is used to load a new instruction into the instruction register. The new instruction must be scanned in using the Shift-IR state. The load occurs on the falling edge of TCK. The Pause-DR and Pause-IR states are provided to allow shifting through the test data and/or instruction registers to be momentarily paused. Boundary Scan Instructions The following is an description of the standard instructions. Each instruction selects an serial test data register path between input, TDI and output, TDO. BYPASS The bypass instruction shifts data from input, TDI to output, TDO with one TCK clock period delay. The instruction is used to bypass the device. EXTEST The external test instruction allows testing of the interconnection to other devices. When the current instruction is the EXTEST instruction, the boundary scan register is place between input, TDI and output, TDO. Primary device inputs can be sampled by loading the boundary scan register using the Capture-DR state. The sampled values can then be viewed by shifting the boundary scan register using the Shift-DR state. Primary device outputs can be controlled by loading patterns shifted in through input TDI into the boundary scan register using the Update-DR state. SAMPLE The sample instruction samples all the device inputs and outputs. For this instruction, the boundary scan register is placed between TDI and TDO. Primary device inputs and outputs can be sampled by loading the boundary scan register using the Capture-DR state. The sampled values can then be viewed by shifting the boundary scan register using the Shift-DR state. IDCODE The identification instruction is used to connect the identification register between TDI and TDO. The device's identification code can then be shifted out using the Shift-DR state.

When this instruction is the current instruction, the boundary scan register is connected between TDI and TDO. During the Capture-DR state, the device identification code is loaded into the boundary scan register. The code can then be shifted out output, TDO using the Shift-DR state. 13.27 Field guide to first packet The following steps are suggested to successfully bring up the PM3386. 1. Ensure proper connections to test equipment have been made. 2. Insure proper power and ground supplies as per specification. Also insure that the required pins have pull-ups or pull-downs as described by this specification. Please also note to tie the PMD_SEL0 and PMD_SEL1 pins to either power or ground. 3. Insure proper clocks are being supplied to the PM3386. 4. Follow the Operation section System Reset procedure. 5. Check Register 0x4H Device Status Register. This register should show the DLL0_RUN and DLL1_RUN signals high. If these signals are not present the most likely issue will be lack of the proper RFCLK or TFCLK respectively. Ensure bits [14] and [15] are set to 1. If not the most likely problem will be that TDI or TMS do not have pull up resistors installed. 6. Check Register 0x5H Reference Out of Lock Status Register. This register should read 0x0. Issues that might cause other values to be read are typically the lack of the CLK125 being present to the device. 7. Check Register 0x6H Data Out of Lock Status Register. This register should read 0x0 if in SERDES mode. If in SERDES mode and this register is not 0x0 the link to the test equipment for the Gigabit Ethernet may not be connected. 8. Prior to enabling the PM3386 set all optional registers to conform to the target application. Please note that there are no registers that need to be set if the user is just trying to get data through the device for debug purposes. 8. Enable the desired channel that data is to be passed on. This is done as described above in the Enabling and Disabling Data Flows sections.

The link device throughout this example holds the RENB asserted signaling to the PM3386 that it can accept data. In cycle 2 the PM3386 asserts RSX to qualify the in-band address presented on the RDAT bus. In cycle 3 RVAL is asserted qualifying both the valid data on RDAT as well as the RSOP signal indicating the start of a frame. The PM3386 bursts 16 bytes over cycles 3,4,5, and 6. In cycle 7 the PM3386 re-arbitrates to channel 0. The PM3386 signals the link device of the change by asserting the RSX signal qualifying the in-band address on the RDAT bus. In cycle 8 and 9 bytes are transferred to the link device. However in cycle 9 the PM3386 ceases the transfer and asserts the REOP, RMOD, and RERR signals. In this case the RERR signal indicates that an error has occurred on this transfer. In cycles 10 and 11 the PM3386 pauses transfer. This can be noted by the de-assertion of the RVAL signal. In cycle 12 the PM3386 resumes transfer for channel 1. It should be noted that RPRTY will indicate the parity across the RDAT bus when RVAL or RSX are asserted. Figure 11 1 - PM3386 POS-PHY L3 Receive Logical Timing 2 3 4 5 6 7 8 9 10 11 12 13 14 15 RFCLK RENB RSX RSOP REOP RERR RMOD[1:0] RDAT[31:0] 00 1 B0- B4-B B8- 10 B12 0 A0-A A4- 00 1 B16 B20 B2 RPRTY RVAL Figure 12 is an example of the PM3386 being paused by the upper level link device. In cycle 1 the PM3386 concludes a transfer to channel 1. In cycle 2 the PM3386 PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 270 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER pauses. In this case no data was available for transfer. In cycle 3 the PM3386 indicates to the link device the in-band address for the upcoming data transfer. Note that even though RENB is asserted in cycle 3 that the PM3386 will not hold RSX asserted as RENB was not de-asserted (logic high) during cycle 2. RENB does however have an effect on RVAL in cycle 4. Since the link device indicates that it requires a pause in cycles 3 and 4 the PM3386 will hold the RVAL signal high and will not advance the valid data until one cycle (pos-edge of cycle 6) after the assertion of RENB. RENB is asserted in cycle 5 therefore data can be considered valid on the positive edge of cycle 6. Data transfer continues in cycle 7 and 8. In cycle 9 the PM3386 pauses. This is indicated by the de-assertion of RVAL. In cycle 10 the PM3386 concludes the transfer of this frame. In this case the frame is in error and is indicated such by the assertion of RERR and REOP. In cycle 11 the PM3386 indicates the in-band address to the link device. Since the link device indicated a pause in cycle 10 by de-asserting RENB the PM3386 will hold the RSX signal high and will not change the value of the RDAT bus until one cycle (pos-edge of 14) after the assertion of RENB. The PM3386 resumes sending data on RDAT in cycle 15.

It is acceptable for the point of view of the PM3386 that the link layer device deassert RENB at any time and for any length of time. In the first case RENB is de-asserted in cycle 3. The PM3386 captures the de-assertion on the rising edge of RFCLK on the beginning of cycle 4. Because of the RENB induced pause in cycle 5 the data on the RDAT bus will remain unchanged . In the second case the RENB signal is de-asserted in cycle 8. Again note that the data in cycle 10 will be held as the RENB de-assertion causes a pause on the data transfer on the RDAT bus. In the third case RENB is de-asserted in cycle 12. Note that in cycle 14 both the RVAL and RSOP as well as the data on RDAT are held unchanged because of the paused induced by the de-assertion of RENB. Figure 13 - PM3386 POS-PHY L3 Receive Logical Timing Cases A 1 2 3 1 B0- B4- 4 5 6 7 8 9 10 11 12 13 14 15 16 RFCLK RENB RSX RSOP REOP RERR RMOD[1:0] RDAT[31:0] B8-B11 1 B0 B4-B7 1 B0-B3 B4- RPRTY RVAL Figure 14 continues to look at the POS-PHY Level 3 receive interface as it is paused by the RENB signal. In case 1 the RENB is de-asserted in cycle 1 and 2. This causes the PM3386 to hold the RSX value as well as the in band address on the RDAT bus until assertion of RENB. In case 2 the RENB signal is de-asserted toward the end of a packet. In cycle 8 this has no effect on the previously finished frame. The same holds true in case 3 as is shown by cycle 11 RENB de-assertion to have no effect. However in case 4 we see that RENB PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 272 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER de-assertion in cycle 14 and 15 cause the RDAT, REOP, RERR, RMOD, RPRTY, and RVAL signals to hold value until the sampled assertion of RENB.

Throughout the below transfer the STPA signal from the PM3386 stays asserted signaling the link device that there is room in the PM3386 FIFOs for the incoming frame. On cycle 1 the link device asserts TSX indicating the validity of the in-band address on the TDAT[7:0] bus pins. On cycle 2 the link starts the data transfer. The data transfers are qualified by TENB and the beginning of the frame is indicated by the TSOP being asserted. On cycle 3 the link device pauses the data transfer by de-asserting TENB. On cycles 4, 5, and 6 the link finishes the first burst of the frame and re-arbitrates channels to channel zero on cycle 7. Note that the link device does not assert TEOP in cycle 6 as it is not the end of a frame. On cycle 7 the link address channel zero and initiates data transfer on cycles 8 and 9. On cycle 9 the link ends the transfer with the TEOP. In this case the frame also contains an error so the TERR signal is asserted. TMOD qualifies the number of valid bytes on TDAT during cycle 9. Cycle 10 and 11 are optional link induced pause cycles. On cycle 12 the link arbitrates back to channel 1 and starts data transmission for that channel over the TDAT bus. Note that TSOP is not asserted in cycle 13 as it is not the start of frame.

DTPA[1:0] is a direct indication from the PM3386 egress FIFO fill levels. STPA will indicate the PM3386 FIFO fill levels associated with the generated in-band address. PTPA will indicate the PM3386 FIFO fill levels for the polled channel via the TADR input. In all three cases all three indications are derived directly from the FIFO fill levels. Using all three indication methods are not a prerequisite for a given design. It is up to the implementer to choose which methods work for the given design implementation. Figure 16 is an example PM3386 POS PHY Level 3 egress flow control signals. Included in the diagram is a representation of the egress FIFO fill levels. The signals are labeled FIFO # 0 and FIFO # 1. These states are used to help illustrate the relationship between the DTPA[1:0], STPA, and PTPA signals.

RX_DV shall be asserted continuously from the first recovered octet of the frame through the final recovered octet and shall be negated prior to the first rising edge of RX_CLK that follows the final octet.

The microprocessor bus can be used in a multiplexed fashion with both address and data being present on the board system bus or in a de-multiplexed fashion with the address and data on separate busses upon the system board. Figure 21 represents the PM3386 microprocessor interface during a demultiplexed read access. At point A the host drives the A bus with a valid read address. It is important to note that the host must drive a valid address on the A bus prior to assertion of the RDB signal. At point B the PM3386 is instructed to take ownership of the D bus by the assertion (active low) of CSB and RDB. Both CSB and RDB need to be asserted if accessing the PM3386. At point C the PM3386 drives the D bus with invalid data. At point D the PM3386 will present valid data to the host. The delay between point C and D is the internal access PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 277 PM3386 RELEASED DATASHEET PMC-1991129 ISSUE 7 DUAL GIGABIT ETHERNET CONTROLLER time for reading the register. The PM3386 will continue to present valid data to the host until RDB or CSB are de-asserted. At point E the PM3386 is instructed by the host to relinquish control of the D bus by the de-assertion of RDB. At point F the PM3386 releases control over the D bus. The address on the A bus must be held for the entire read cycle. In this case at point G the host releases the valid address on the A bus. Please refer to the A.C. timing section for setup and hold time requirements.

At point A the host drives the A bus with a valid write address. It is important to note that the host must drive a valid address on the A bus prior to assertion of the WRB signal. At point B the host asserts (active low) both the CSB and WRB signals. At point C the host drives the D bus with valid write data. It is important to note that the host must drive valid data on the D bus prior to de-assertion of the WRB or CSB signals. At point D the host de-asserts WRB causing the PM3386 to internally write the data into the destined register. At point E the host removes the valid write data from the D bus. At point F the host removes the valid write address from the A bus.

The signal System Bus is used to illustrate the use of a shared system bus that might be implemented on the system board. The host presents a valid read address at points A and F. This address is latched into the PM3386 on the falling edge of ALE at point G. The host then turns the bus control over to the PM3386 by asserting RDB at point I. At point J the PM3386 starts to drive the bus with invalid data. At point K valid data is presented to the D bus and the System Bus. Valid data will continue to be present on the D bus until the host removes the D bus control from the PM3386 by de-assertion of the RDB signal at point L. At point M the PM3386 no longer drives the D or System Bus.
