12 Sundance Technology ST201 PRELIMINARY draft 2 E XPANSION ROM INTERFACE The ST201 provides su pport f or an optional Expan- sion ROM. The ST201 supports th e A tmel AT29C512 (64K x 8) Flash EPRO M device. T he Expansion ROM is configured through the PCI configuration register, which maps the ROM into the memory space of the host system .

Setting the ReceiveBroadcast and ReceiveMulticast bits in the ReceiveMode register will allow the ST201 to receive all broadcast and m ulticast frames, respectively . The ReceiveMultic- astHash bit in ReceiveMode enables a filtering mechanism for Ethernet multicast frames.
14 Sundance Technology ST201 PRELIMINARY draft 2 T XDMA AND FRAME TRANSMISSION The TxDMA block transfers frame data from a host system to the ST201 based on a linked list of frame descriptors called T FDs . The frame to be transmit- ted is divided into data fragments (or buffers) within the host system ’ s memory.

19 Sundance Technology ST201 PRELIMINARY draft 2 STATISTIC S T he ST201 implements 16 statistics counters of various widths. Each statistic implemented com- plies to the corresponding definition given in the IEEE 802.3 standard. S etting the StatisticsEnable bit in the MACCtrl register enables the gathering of statistics.

The ST201 provides a set of registers that control the PCI burst behavior. These registers allow a trade-off to be made between PCI bus efficiency and under run/ overrun frequency.

W hen the ST201 detects a W ake Packet, it signals a wake event on PMEN (if PMEN assertion is enabled), and sets the WakePktEvent bit in the W akeEvent register. The ST201 can sig- nal that a w ake event has occurred w hen it receives a pre-defined frame from another station.
