Description
The AT79C1010 is an Ethernet switch controller that performs Layer 2 Switching
according to IEEE 802 standards. It adopts the crossbar architecture to complete the
function of packets switching between 4 MII ports. The mechanism of this switch is
“learning & forwarding”, and the embedded MAC address table ensures the imple-
mentation of this function. It can attain wire speed when it's used as a fast Ethernet
switch.
