Operation Mode Configuration
W89C841F can be configured to 3 different operation modes for different applications. In the following
table, the assignment of pins CONFIG[1:0] and ModeSel[2:0] is listed.

In the normal mode, W89C841F is used in the NIC application. In the MAC controller mode,
W89C841F that is used as a MAC controller plus HomePHY that is used as a transceiver implement a
HomePNA card. In the PHYceiver mode, an application like LAN On Motherboard (LOM) is
implemented by W89C841F that is used as a single PHYceiver plus PC chipset.
PHYceiver
An internal PHYceiver is embedded in W89C841F. It is compatible with IEEE802.3 10-BAST-T,
100BASE-TX and 100BAST-FX. W89C841F can be configured to twist pair interface or fiber interface.
Auto-negotiation and auto-crossover function is supported. W89C841F provides 3 LEDs to indicate
Link/Activity, Speed and Duplex/Collision status.
Direct Memory Access Function
On receiving a data packet, the receive DMA function will
transfer these data from the internal receive
FIFO which has a size of 2k bytes to the host memory with the assistance of the on-chip PCI bus
master. During the transaction cycle, the media access controller (MAC) requests the receive DMA
state machine to move the data in the receive FIFO onto the PCI bus, and then move it to the host
memory.
