micrel, inc. ksz8692mpb/KSZ8692XPB march 2010 18 m9999-031810-4.0 pci interface the ksz8692mpb/KSZ8692XPB integrates a pci- to-ahb bridge solution for inte rfacing with 32-bit pci, including minipci, and cardbus devices where it is common for 802.11 x-based wireless products. the pci-ahb bridge supports two modes of operation in the pci bus environment; host bridge mode and guest bridge mode. in the host bridge mode, the arm processor acts as the host of the entire system. it configures ot her pci devices and coordinates their transactions, including initiating transactions between the pci devices and ahb bus subsystem. an on-chip pci arbiter is included to determine the pci bus ownership among up to three pci master devices. in guest bridge mode, all of the i/o registers are programmed by either the external host cpu on the pci bus or the local arm host processor through the ahb bus and the ksz8692m pb/KSZ8692XPB can be configured by either the arm or the pci host cpu. in guest bridge mode, the on-chip pci arbiter is disabled. in both cases, the ksz8692mpb/KSZ8692XPB memory subsystem is accessible fr om either the pci host or the arm processor. communications between the external host cpu and the arm processor is accomplished through message passing or through shared memory. ? compliant to pci revision 2.3 ? support 33 and 66mhz, 32-bit data pci bus ? support 32-bit minipci or cardbus devices ? supports both regular and memory-mapped i/o on the pci interface ? ahb bus and pci bus operate at independent clock domains ? supports big endian and little endian on ahb ? pci bus round robin arbiter for three external masters (for ksz8692mpb only) ? pci bus arbiter for one extern al master (for KSZ8692XPB only) ? supports high speed bus request and bus parking ? dedicated dma channel for bulk data transfer to/from ddr memory ethernet mac ports (port 0 = wan, port 1 = lan) the ksz8692mpb/KSZ8692XPB integrates two ethernet controllers that operate at 10 and 100 mbps. each controller has an interface that operates as mii to an external 10/100 ph y to complete ethernet network connectivity. an integrated 25 mhz clock eliminates external crystal or oscillator requi rement for phy to reduce cost. integrated 2-pin (mdc & mdio) station manager allows arm processor to access phy registers and pass contro l and status parameters. wake-on-lan is supported as part of the power management mechanism. each port has a dedicated mib counter to accumulate statistics for received and transmitted traffic. ? ieee 802.3 compliant mac layer function ? mii interface compliant to clause 22.2.4.5 of the ieee 802.3u specification ? 10/100 mbps half and full-duplex operation ? automatic crc generation and checking ? automatic error packet discard ? supports ipv4 header and ipv4/ipv6 tcp/udp checksum generation to offload host cpu ? supports ipv4 header and ipv4/ipv6 tcp/udp checksum error detection ? supports 32 rules acl filtering ? maximum frame length support is 2000 by te at wan port and 9k-byte at lan port ? contains large independent receive and transmit fifos (8kb receive / 8kb transmit at wan and 24kb receive / 22kb transmit at lan) for back-to-back packet rece ive, and guaranteed no-under run packet transmit ? data alignment logic and scatter gather capability ? configurable as mac or phy mode ? separate transmit and receive dma channels for each port wake-on-lan wake-up frame events are used to wake the system whenever meaningful data is presented to the system over the network. examples of meaningful data include the reception of a magic packet, a management request from a remote administrator, or simply network traffic di rectly targeted to the local system. in all of these instances, the network device i s downloaded from: http:///
micrel, inc. ksz8692mpb/KSZ8692XPB march 2010 19 m9999-031810-4.0 pre-programmed by the policy owner or other software with information on how to identify wake frames from other network traffic. a wake-up event is a request for hardware and/or software ex ternal to the network device to put the system into a powered state. a wake-up signal is caused by: 1. detection of a change in the network link state 2. receipt of a network wake-up frame 3. receipt of a magic packet there are also other types of wake-up ev ents that are not listed here as manufact urers may choose to implement these in their own way. link change link status wake events are useful to indicate a change in the networks availability, especially when this change may impact the level at which the system should re-enter the sleeping state. for example, a change from link off to link on may trigger the system to re-enter sleep at a higher level (d2 versus d3 1 ) so that wake frames can be detected. conversely, a transition from link on to link off may trigger the system to re-enter sleep at a deeper level (d3 versus d2) since the network is not currently available. wake-up packet wake-up packets are certain types of packets with specific crc values that a system recognizes to as a wake up frame. the ksz8692mpb/KSZ8692XPB supports up to four user defined wake-up frames on each network controller port: magic packet magic packet technology is used to remotely wake up a sl eeping or powered off pc or device on network. this is accomplished by sending a specific pack et of information, called a magic packet frame, to a node on the network. when a pc or device capable of receiving the specific frame goe s to sleep, it enables the magic packet rx mode in the networkcontroller, and when the networkcontroll er receives a magic packet frame, it will alerts the system to wake up. magic packet is a standard feature integrated into the ksz8692mpb/KSZ8692XPB. the controller implements multiple advanced power-down modes including magic packet to conserve power and operate more efficiently. once the ksz8692mpb/KSZ8692XPB has been put into magic pa cket enable mode, it scans all incoming frames addressed to the node for a specific data sequence, which indica tes to the controller this is a magic packet (mp) frame. a magic packet frame must also meet the basic requirements for the networktec hnology chosen, such as source address (sa), or destination a ddress (da), which may be the rece iving stations ieee address or a multicast or broadcast address and crc. the specific sequence consists of 16 duplications of the ieee address of this node, with no breaks or interruptions. this sequence can be located anywhere within the packet, but must be preceded by a sync hronization stream. the synchronization stream allows the scanni ng state machine to be much simpler. the synchronization stream is defined as 6 bytes of xoffffh. the device will also accept a broadcast frame, as long as the 16 duplications of the ieee address match the address of the machine to be awakened. example: if the ieee address for a particular node on a network is 11h 22h, 33h, 44h, 55h, 66h, the networkcontroller would be scanning for the data sequence (a ssuming an ethernet frame): destination source C misc - .: ff ff ff ff ff ff - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - 11 22 33 44 55 66 - misc - circ. there are no further restrictions on a magi c packet frame. for instance, the sequence could be in a tcp/ip packet or an ipx packet. the frame may be bridged or routed across the net work without affecting its ability to wake-up a node at the 1 references to d0, d1, d2, and d3 are power management states defined in a similar fashion to the way they are defined for pci. for more information, refer to the pci specification at www.pcisig.com/specifications/conventional/pcipm1.2.pdf. downloaded from: http:///
