Each of the transceivers complies with the IEEE802.3, IEEE802.3u, and IEEE802.3x specifications. The transceivers are designed in DSP approach in 0.18um technology; they have high noise immunity and robust performance. IP178C/IP178CH operates in store and forward mode. It supports flow control, auto MDI/MDI-X, CoS, port base VLAN, bandwidth control, DiffServ, SMART MAC and LED functions, etc. Each port can be configured as auto-negotiation or forced 10 Mbps/100 Mbps, full/half duplex mode. Using an EEPROM or pull up/down resistors on specific pins can configure the desired options. Besides an 8-port switch application, IP178C/IP178CH supports one MII/RMII ports for router application, which supports 7 LAN ports and one WAN port. The external MAC can monitor or configure IP178C/IP178CH by accessing MII registers through SMI. MII/RMII port also can be configured to be MAC mode. It is used to interface an external PHY to work as an 8+1 switch. IP178CH supports two fiber ports with far end fault function. 1/93 Copyright (c) 2004, IC Plus Corp.

Its link partner will defer transmission after detecting the jam or pause frame. A port of IP178C/IP178CH defers transmission when it receives a jam or a pause frame. IP178C/IP178CH issues pause control frame (Pause On, time slot count = 0xffff) to remote station when the output queue of the destination port is higher than high water mark threshold. When the output queue of the destination port is lower than low water mark threshold, IP178C/IP178CH issues pause control frame (Pause Off, time slot count = 0) to restart transmition. Besides, IP178C/IP178CH provides an additional protect function, when it issues continuous 16 times of Pause ON frame (network abnormal), no more Pause ON frame will be send. When CoS is enabled, IP178C/IP178CH may disable the flow control function for a short term to guarantee the bandwidth of high priority packets. A port disables its flow control function for 2 ~ 3 seconds when it receives a high priority packet. It doesn't transmit pause frame or jam pattern during the period but it still responses to pause frame or jam pattern. The flow control function can be enabled by pulling up pin 75 X_EN or by programming MII register 30.1.10. 32/93 Copyright (c) 2004, IC Plus Corp.

Each port can be configured individually by programming MII register 30.31[8:0] or EEPROM 63[0] and 62[7:0]. User has to reset IP178C/IP178CH by writing 16'h55AA to MII register 30.0 after enabling this function. IP178C/IP178CH locks first MAC address if the function is enabled. Any packet with MAC address not equal to the locked one will be dropped. User has to turn off aging function when using the port locking function. Aging function can be disabled by pulling low pin 76 AGING or programming register 30.1[3:2]. 34/93 Copyright (c) 2004, IC Plus Corp.

A port is limited to communicate with other ports within the same group when the function is enabled. Frames will be limited in a VLAN group and will not be forwarded out of this VLAN group. A port can be assigned to one or more VLAN groups. The members (ports) of a VLAN group are assigned by programming EEPROM register 64[7:0]~81[7:0], or MII register 31.0[8:0]~31.8[8:0]. The VLAN function can be active even if there is no EEPROM. IP178C/IP178CH supports an easy way to enable a sub set VLAN function without programming registers. A default configuration of VLAN is adopted if pin 79 VLAN_ON is pulled high. The VLAN duration is shown in the following table. The setting in register takes precedence of the setting on pins. VLAN_ON 0 1 EXTMII_EN X 0 Configuration Function disabled VLAN groups: (P0, P7), (P1, P7), (P2, P7), (P3, P7), (P4, P7), (P5, P7), (P6, P7) VLAN groups: (P0, MII), (P1, MII), (P2, MII), (P3, MII), (P4, MII), (P5, MII), (P6, MII), (P7, MII) 1 1 Note: P0 means port 0. P7 means port7. MII means MII port. 35/93 Copyright (c) 2004, IC Plus Corp.

Forward the packet without modification Priority-tagged (VLAN ID=0) Strip tag Calculate new CRC VLAN-tagged Strip tag Calculate new CRC 2.6 Tag VLAN If tag VLAN function is enabled (MII register 30.13[3] TAG_VLAN_EN is logic high), IP178C/IP178CH forwards a packet according to MAC address table and one of the sixteen VLAN output port masks, defined in MII register 30.14~30.29. One of the sixteen VLAN output mask is selected by VID index, which is four bits selected from VID field in a tag. VID index is defined in MII register 30.13[2:0] VID_SEL. For example, VLAN output port mask 1 is selected if VID index selected by VID_SEL is equal to 1. IP178C/IP178CH handles an un-tagged packet using the default VLAN tag value of its source port. A packet with VID equal to 12'b0 will be handled as un-tag frame. 36/93 Copyright (c) 2004, IC Plus Corp.

One is port base priority function and the other is frame base priority function. IP178C/IP178CH supports two levels of priority queues. A high priority packet will be queued to the high priority queue to share more bandwidth. The ratio of bandwidth of high priority and low priority queue is defined in MII register 30.1[15] or EEPROM 3[7]. 2.9.1 Port base priority The packets received from high priority port will be handled as high priority frames if the port base priority is enabled. It is enabled by programming the corresponding bit in MII register 31.0[9]~31.8[9] or EEPROM register 65[1] ~81[1]. Each port of IP178C/IP178CH can be configured as a high priority port individually. 2.9.2 Frame base priority VLAN tag and TCP/IP TOS IP178C/IP178CH examines the specific bits of VLAN tag and TCP/IP TOS for priority frames if the frame base priority is enabled. The packets will be handled as high priority frames if the tag value meets the high priority requirement, that is, VLAN tag bigger than 3 or TCP/IP TOS field not equal to 3'b000. It is enabled by programming the corresponding bit in MII register 31.0[10]~31.8[10] or EEPROM register 65[2]~81[2]. The frame base priority function of each port can be enabled individually. IP178C/IP178CH supports an easy way to enable a sub set of CoS function without programming EEPROM or MII registers. Port 6 and port 7 can be set as high priority ports if pin 100 P6_7_HIGH is pulled high. Frame base priority function of all ports is enabled if pin 99 COS_EN is pulled high. The setting in register takes precedence of the setting on pins. VLAN field TCI definition: Bit[15:13]: User Priority 7~0 Bit 12: Canonical Format Indicator (CFI) Bit[11~0]: VLAN ID.
