Modified cut-through switch mode: IP113M LF begins to forward a frame after the first 64 bytes data received. TP port should be forced at 100M at this mode. Converter mode: Incoming frames are not buffered in IP113M LF to achieve the min latency. Both TP port and fiber port of IP113M LF should work at 100M full duplex in this mode. If TP port is linked at half duplex, the total length of UTP cable and fiber should be less than 60 meters to meet the requirement of CSMACD in IEEE802.3. Converter mode with auto-change-forward function: IP113M LF will change forward mode itself if it detects the speed is different in TP port and FX port. In converter mode, IP113M LF forwards IEEE802.3x pause frame directly. In the other modes, IP113M LF doesn’t forward IEEE802.3x pause frame directly, it sends out pause frame when its internal buffer is full.

2.1 Data forwarding

IP113M LF supports three types of data forwarding mode, store & forward mode, modified cut-through mode and pure converter mode. It can forward a frame despite of its address and CRC error. IP113M LF begins to forward the received data when it receives the frame completely. The latency depends on the packet length.

2.1.1 Modified cut-through mode

IP113M LF begins to forward the received data when it receives the first 64 bytes of the frame. The latency is about 512 bits time width. The maximum packet length is up to1600 bytes in this mode. Please refer to pin description of FAST_FWD for configuration information.

2.1.2 Pure converter mode

IP113M LF operates with the minimum latency in th is mode. The transmission flow does not wait until entire frame is ready, but instead it forwards the received data immediately after the data being received. Both transceivers are interconnected via internal MIIs and the internal switch engine and data buffer are not used. Both TP port and fiber port of IP113M LF should work at 100M full duplex in this mode. If TP port is linked at half duplex, the total length of UTP cable and fiber should be less than 60 meters to meet the requirement of CSMACD in IEEE802.3. The packet length is not limited at this mode. Please refer to pin description of DIRECT_WIRE for configuration information. In converter mode, it is strongly recommended that both TP port and fiber port of IP113M LF should work at 100M full duplex. If TP port is linked at half duplex, the UTP cable length should be less than 30 meters to meet the requirement of CSMACD in IEEE802.3.

2.1.3 Fragment forwarding

IP113M LF forwards CRC error packet s but it will filter fragments when it works in modified cut-through mode. IP113M LF forwards fragments if user turns on bit 3 of MII register 20.

2.2 TP port force mode

The TP port of IP113M LF can work at auto mode or force mode. The following table shows all of the combination of its TP port.

2.3 Remote management

IP113M LF supports remote monitor and configuratio n function. IP113M LF implement the function by exchanging maintenance frames on fiber ports betw een two IP113M LF’s. The maintenance frames are not forwarded to TP ports. The frame format follows the TS-1000 standard.

back test mode. 1.3 Central IP113M LF goes to CST1 state and begins sending 15 frames in 64 bytes. 1.4 Remote IP113M LF loops back the received frames at the TP port’s PMD sub-layer. 1.5 Central IP113M LF checks the loop back frames and reports the result.

2 The LED pin LED_RMT_TP_LINK is Flash (on 80ms / off 20ms) during the auto loop back test

period (AUTO_TEST is “1”).

3 The LED pin LED_RMT_TP_SPD indicates the loop back test complete (on) (when

AUTO_TEST is “1”). The LED pin LED_RMT_TP_FDX indicates the loop back test ok (on) (when AUTO_TEST is “1”) 4 If another auto loop back test is needed, set AUTO_TEST to “0” and then “1”. That is, AUTO_TEST is triggered whenever there is a low-to-high transition on this pin.

2.5 Remote monitor without SMI programming

2.5.1 Auto sends (Status change notice)

IP113M LF sends out status frame without receivin g status request frame if pin AUTO_SEND is pulled high. It sends out the first status frame onto the fiber port when the link status of fiber port has established. It sends out status frames when the status on TP port has changed. IP113M LF supports two types of frame. For a TS-1000 maintenance frame, C[9:8] is 2’b10 and S[15:0] is defined as that in TS-1000 standard. For an ICplus maintenance frame, C[9:8] is 2’b11 and S[15:0] is the content of MII register 22. It carries ICplus private defined information. User can select the frame type by programming MII register 20.10. Central IP113M LF uses the mechanism to get the status of the remote IP113M LF even if there is no SMI programming. Option A Central IP113M LF sends indication frames to terminal IP113M LF if its status is changed. IP113M LF (terminal) IP113M LF (central) FXTP TP Maintenance frame status changed !! Option B Terminal IP113M LF sends indication frames to central IP113M LF if its status is changed. IP113M LF (terminal) IP113M LF (central) FXTP TP Maintenance frame status changed !!

2.6 Link fault pass through

When link fault pass through function is enabled, link status on TX port will inform the FX port of the same device and vice versa. From the link fault pass through procedure illustrates in the figure below, if link fail happens on IP113M LF’s TX port (1), the local FX port sends non-idle pattern to notice the remote FX port (2). The remote FX port then forces its TX port to link failed after receiving the non-idle pattern (4). In other words, this mechanism will alert the link fault status of local TX port to the remote converter’s TX port, and the link status of the remote TX port will become off. Link status LED will also be off for both IP113M LF and its link partner.

2.7 EEPROM – store the initial value

IP113M LF supports two ways to load initial value of MII registers. The procedure is illustrated as below. IP113M LF 1. IP113M LF reads the default setting of MII register from pins pins IP113M LF 2. IP113M LF updates the default setting of MII by reading EEPROM. If there exists an EEPROM. EEPROM IP113M LF 3. After reading EEPROM, IP113M LF is virtually isolated from the EEPROM. Micro-controller can program both MII register and EEPROM. EEPROM uC MDC, MDIO SCL, SDA IP113M LF 4. IP113M LF reloads the content of EEPROM to recover the value in MII registers programmed by Micro-controller after power on reset. EEPROM 26/58 April 9, 2007 Copyright © 2004, IC Plus Corp.

Pin(0) The default value is “0” and it depends on the setting of its corresponding pin. The basic MII registers 0 MII NAME R/W DESCRIPTION DEFAULT MII control register (address 00h)

0.15 Reset R/W

1 = PHY reset 0 = normal operation This bit is self-clearing, IP113M LF will return a value of 1 before reset process is completed, and will not accept any write transaction of MII Management within reset process. Make any change to Auto-Negotiation or speed mode will cause IP113M LF reset again.

0.14 Loop back R/W 1 = Loop back mode

0 = normal operation When this bit is set, IP113M LF will be isolated from the network media, and the assertion of TXEN at the MII will not transmit data on the network. All MII transmit data path will return to MII receive data path in response to the assertion of TXEN. MII COL signal will remain de-asserted at all times, unless bit 0.7 (Collision Test) is set. Use has to wait about 100ms for loop back path ready.
