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.
