The 

ENC28J60

is a stand-alone Ethernet controller with an industry standard Serial

Peripheral Interface (SPI™). It is designed to serve as an Ethernet network interface
for any controller equipped with SPI. 

The 

ENC28J60

meets all of the IEEE 802.3 specifications. It incorporates a number

of packet filtering schemes to limit incoming packets. It also provides an internal
DMA module for fast data throughput and hardware assisted IP checksum calcula-
tions. Communication with the host controller is implemented via two interrupt pins
and the SPI, with data rates of up to 10 Mb/s. Two dedicated pins are used for LED
link and network activity indication.

This library is designed to simplify handling of the underlying hardware (

ENC28J60

).

It works with any AVR MCU with integrated SPI and more than 4 Kb ROM memory.

SPI Ethernet library supports: 

- IPv4 protocol. 
- ARP requests. 
- ICMP echo requests. 
- UDP requests. 
- TCP requests (no stack, no packet reconstruction). 
- packet fragmentation is NOT supported. 

Note: Prior to calling any of this library routines, Spi_Rd_Ptr needs to be initialized
with the appropriate SPI_Read routine.

Note: The appropriate hardware SPI module must be initialized before using any of
the SPI Ethernet library routines. Refer to SPI Library.
