* Data sheets and programming docs for the DP83840 are available at

|
|
* The DP83840 is capable of both 10 and 100Mbps ethernet, in both
|
|
* half and full duplex mode. It also supports auto negotiation.
|
|
*
|
|
* But.... THIS THING IS A PAIN IN THE ASS TO PROGRAM!
|
|
* Debugging eeprom burnt code is more fun than programming this chip!
