2. GENERAL DESCRIPTIONS
The MX98715 controller is an IEEE802.3u compliant single chip 32-bit full duplex, 10/100Mbps highly integrated Fast Ethernet combo solution, designed to address high performance local area networking (LAN) system application requirements. MX98715's PCI bus master architecture delivers the utilimized performance for future high speed and powerful processor technologies. In other words, the MX98715 not only keeps CPU utilization low while maximizing data throughput, but it also optimizes the PCI bandwidth providing the highest PCI bandwidth utilization. To further reduce maintenance costs the MX98715 uses drivers that are backward compatible with the original MXIC MX98713 series controllers. The MX98715 contains a PCI local bus glueless interface, a Direct Memory Access (DMA) buffer management unit, an IEEE802.3u-compliant Media Access Controller (MAC), large Transmit and Receive FIFOs, and an on-chip 10 Base-T and 100 Base-TX transceiver simplifying system design and improving high speed signal quality. Full-duplex operation are supported in both 10 Base-T and 100 Base-TX modes that increases the controller's operating bandwidth up to 200Mbps. Equipped with intelligent IEEE802.3u-compliant auto-negotiation, the MX98715-based adapter allows a single RJ-45 connector to link with the other IEEE802.3u-compliant device without re-configuration. In MX98715, an innovative and proprietary design "Adaptive Network Throughput Control" (ANTC) is built-in to configure itself automatically by MXIC's driver based on the PCI burst throughput of different PCs. With this proprietary design, MX98715 can always optimize its operating bandwidth, network data integrity and throughput for different PCs. MXIC MX98715 features Remote-Wake-Up capability that enables a wide range of wake-up capabilities, including the ability to customize the content of specified packet which PC should to respend to, even when it is in a low-power state. PCs and workstations could take advantage of these capabilities of being waked up and serviced simultaneiously over the network by remote server or workstation. It helps organizations reduce their maintenance cost of high-performance business PCs. With its on-chip support for both little and big endian byte alignment, MX98715 can also address non-PC applications.

Description Software Reset, when set, MX98715 resets all internal hardware with the exception of the configuration area and port selection. Internal bus arbitration scheme between receive and transmit processes. The receive channel usually has higher priority over transmit channel when receive FIFO is partially full to a threshold. This threshold can be selected by programming this bit. Set for lower threshold, reset for normal threshold. Descriptor Skip Length, specifies the number of longwords to skip between two descriptors. Big/Little Endian, set for big endian byte ordering mode, reset for little endian byte ordering mode, this option only applies to data buffers Programmable Burst Length, specifies the maximum number of longwords to be t r ansferred in one DMA transaction. default is 0 which means unlimited burst length, possible values can be 1,2,4,8,16,32 and unlimited . Cache Alignment, programmable address boundaries of data burst stop, MX98715 can handle non-cache- aligned fragement as well as cache-aligned fragment efficiently. Transmit Auto-Polling time interval, defines the time interval for MX98715 to performs transmit poll command automatically at transmit suspended state.

Full-Duplex Mode, set for simultaneous transmit and receive operation, heart beat check is disabled, TDES0<7> should be ignored, and internal loopback is not allowed. This bit controls the value of bit 6 of link code word . Pass All Multicast, set to accept all incoming frames with a multicast destination address are received. Incoming frames with physical address are filtered according to the CSR6<0> bit. Promiscuous Mode, any incoming valid frames are accepted, default is reset and not affected by software reset. Start/Stop Backoff Counter, when reset, the backoff timer is not affected by the network carrier activity. Otherwise, timer will start counting when carrier drops. Inverse Filtering, read only bit, set to operate in inverse filtering mode, only valid during perfect filtering mode. Pass Bad Frames, set to pass bad frame mode, all incoming frames passed the address filtering are accepted including runt frames, collided fragments, truncated frames caused by FIFO overflow. Hash-Only Filtering Mode , read only bit, set to operate in imperfect filtering mode for both physical and multicast addresses. Start/Stop Receive, set to place receive process in running state where descriptor acquisition is attempted from current position in the receive list. Reset to place the receive process in stop state. Hash/Perfect Receive Filtering Mode, read only bit, set to use hash table to filter multicast incoming frames. If CSR6<2> is also set, then the physical addresses are imperfect address filtered too.
