-// Title : Microchip ENC28J60 Ethernet Interface Driver
-// Author : Pascal Stang (c)2005
-// Created : 9/22/2005
-// Revised : 9/22/2005
-// Version : 0.1
-// Target MCU : Atmel AVR series
-// Editor Tabs : 4

-/// \defgroup enc28j60 Microchip ENC28J60 Ethernet Interface Driver (enc28j60.c)
-/// \code #include "net/enc28j60.h" \endcode
-/// \par Overview
-/// This driver provides initialization and transmit/receive
-/// functions for the Microchip ENC28J60 10Mb Ethernet Controller and PHY.
-/// This chip is novel in that it is a full MAC+PHY interface all in a 28-pin
-/// chip, using an SPI interface to the host processor.
-///
