15/23 mtd658e revision 1.1 05/25/2000 mtd658e myson technology 5.0 functional descriptions the mtd658e is conformed to ieee802.3 chapter 9 and ieee802.3u clause 27 specifications. the mtd658e provides 8 reduced mii interfaces and an embedded two port switch (build_in 64k8 asram on chip) to construct a 10m/100m dual speed hub application. and also, mtd658e can be configured to 5 port mode, it will provide 4 rmii and 1 mii interface. two inter-bus are also provided for stackable 10m/100m dual speed hub application. since mtd658e build_in memory on chip, there are no need any extra memorys in the application board.the mtd658e functions are described as follows: 5.1 repeatation and data handling 8 independent rmii ports integrated with ieee802.3 chapter 9 and ieee802.3u clause 27 repeater functions simultaneously. mtd658e embedded two hub cores (10m and 100m) ,and each dedicated rmii interface port can get per port?s speed information from per port speed input pin, and then mtd658e will switch individual port to their appropriated hub core functions (10m or 100m). the mtd658e receive packets from each rmii ports, and redirect port?s input packet to 10m or 100m hub core according each port?s speed. the internal ieee802.3 chapter 9 or ieee802.3u clause 27 repeater main state machine will starts to repeat the input packet to all ports except the input port. if larger than or equal to two ports have input packet simultaneously, this will be treated as a collision, and mtd658e will assert an arbitrary jam pattern to all ports? output until collision event disappear and net- work is idle. 5.2 partition the mtd658e provides 10m/100m auto partition/reconnection functions to guarantee the network seg- ment performance by means of dectecting a consecutive collisions. each dedicated rmii port has implement a individual 10m/100m auto partition/reconnection state machine. if port?s consecutive colli- sion number over or equal to cclimit (10m cclimit default is 32, 100m cclimit default is 64), this port will be partitioned. reconnection will occurs after a larger than 512 bit time packet was received or transmitted from this partitioned port without any collision. when port is under partition state, mtd658e will not accept any input messages from this port (just monitor input message), but will continue output repeated messages to this partition port. some new partition criterions are also implement, such as long_collision_partition event, jabber_partition event. in 10m/100m partition state machine, longer than 1024 bit time continueous col- lision will force port enter partition state. in 100m partition state machine, if port enter jabber_on state, this port will be partitioned. in 10m, jabber_partition function is not implemented. 5.3 jabber the jabber protect function is used to prevent an illegally long packet reception. after the mtd658e received a longer than 65536 +/- 6.25% bit times packet, this receive port?s receive/transmit path will be inhibited until carrier is no longer detected. 5.4 mii setting due to hub is an half duplex device, the mtd658e need to force all connected phsical devices to work in half duplex environment. the mtd658e will setting all phy?s smi register 4?s half/full duplex bit dur- ing power on, and than restart auto-negotiation procedure to work in half duplex mode. in 8 port mode, the phy?s device id should be setted from 5h04 - 5h0b (port0-7) or from 5h08 -5h0f (port0-7); in 5 port mode, the phy device id should be setted from 5h07 - 5h0b (port0-4) or from 5h0b -5h0f (port0-4). 5.5 inter-bus interface two inter-bus interface are provided by the mtd658e, one is 10m inter-bus interface, the other is 100m inter-bus interface. the inter-bus interface is designed for stackable hub application. for each domain, up to 4 mtd658es can be stacked through this inter-bus without any external arbitration logic. the inter-bus interface includes imaster, idata (100m: use idat<3:0>, 10m: use only idat), reqout, reqin0-2, iclk, iackb, icolb pins. imaster decide which mtd658e can arbitrate the inter-bus, and only one mtd658e?s imaster can be tie high in a stackable hub. idata are synchro-
16/23 mtd658e revision 1.1 05/25/2000 mtd658e myson technology nous with iclk. the mtd658e output reqout to inform inter-bus interface that it need the inter-bus right. when iackb is asserted by inter-bus master after reqout asserted, the mtd658e which asserted reqout will get the bus right and put the transmit data into idata. if the mtd658e did not assert reqout , but iackb is asserted, means this mtd658e can get data from idata bus. when only one mtd658e output reqout to inter-bus interface, iackb will be asserted by inter-bus master device, if larger than two mtd658e?s reqout were asserted, inter-bus master will not assert iackb , but will assert icolb to inform all the connected mtd658es. the inter-bus interface can also be programmed to ext_arb mode, using leddat pin?s jumper set- ting. in this mode, inter-bus interface need an external arbitration logic to arbitrate inter-bus operation. and in this mode, the stackable capability is not limitted by the mtd658e?s reqin pins number. 5.6 10m/100m packet switch the mtd658e inplements a 10/100m two port switch for 10m/100m packet switching. total 2k address entrys are provided for packets? sa learning and da routing; and alsoprovide automatic aging function ( aging time = 300secs). the input packet from 10mhub ( or 100m hub) will be stored to external memory first, while packet is good for forward ( crc chech ok, length = 64bytes ~ 1518bytes or 1522 bytes, and not local packets ) , than forward this packet to 100m hub (or 10m hub). 5.7 uplink switch port the mtd658e can config one switch port as an uplink switch port. when upswen pin is high, and imaster pin is low, one of the intenal switch port is connect to 100m hub, the other is connected to rmii the highest port . in uplink switch mode, the highest port can operate in 10m/100m (in 8 port mode : from spd7 pin; in 5 port mode: from spd4 pin ), and operate in half/full duplex (in 8 port mode: from fd7 pin; in 5 port mode: from fd4 pin). 5.8 memory interface the mtd658e build-in an asynchronous sram as two port switchs? packet buffers, total has 64k byte embedded memory for packet buffering. 5.9 mii management the mtd658e can be managed through mdc, mdio pins. the mtd658e implements 3 mii registers for function control and status report (see section 4.0 on page ). the management frame format is compliant to ieee802.3u clause 22, and the device id is fixed to 5?h1f internally. 5.10 led display the mtd658e implements three display modes, port rx activity, 10/100m domain collision, port parti- tion. the led data pin leddat is high actived. one strobe pin ledclk(24 burst clock/per 42ms) is used to latch serial leddat information, and user can shift the latched data into byte aligned shift register to drive leds. the mtd658e also provide status pins to direct output per port?s receive activity/partition, 100m hub collision, 10m hub collision, embedded asrm memory test fail status. 6.0 registers the mtd658e implements 3 mii registers, define as following tables: table 1. mii registers reg no bits name r/w descriptions default 0 ctlreg0 r/w control register 0 0 reserved. 1b0 1 dispar10 set this bit will disable 10m hub core partition function. 1b0
