Description: m16+cp2200组成的网络接口。
m16使用内部RC振荡8M，如果要提高主频，请注意修改模拟总线读函数。
cp2200模块使用www.icdev.com.cn的，更改pin44连接VCC，即总线复用方式，地址数据复用。
软件编写使用avrstudio4.12+sp4+winavr（avrstudio自带的winavr嵌入方式）。
硬件连接：
m16 | cp2200
PORTA | AD0－7
PB0 | RST
PB1 | CS
PB2 | RD
PB3 | WR
PD2 | INT
PD3 | ALE(A3)
由于采用的是m16做为主控，只能使用总线模拟方式，其读写速度有限，经测试约为双向11.8kBps(90kbps)。
由于ram有限，仅仅采用了332Bytes的数据缓冲做为收发buffer，超过此长度的以太网包将抛弃。
此工程文件仅仅做为cp220x的一个移植范例，高级tcpip应用代码因商业缘故不会提供，请勿找我询问。-m16 cp2200 a network interface.

Description: 本附件为嵌入式Web的相关资料，包括嵌入式Web所用到的网络芯片（Silicon Lab的CP2200或Microchip的ENC28J60），和外围MCU等等的资料，和相关的源码。
有兴趣的朋友也可以动手做一下，主控可以是8051或ARM。实现起来比较简单。
-The attachment for the embedded Web-related information, including the use of embedded Web network chip (Silicon Lab' s CP2200 or Microchip' s ENC28J60), and the external MCU data and so on, and the related source code. Friends also have interest in that may make you, the master could be 8051 or ARM. Relatively simple to achieve.
