m16+cp2200組成的網絡接口。 m16使用內部RC振蕩8M，如果要提高主頻，請注意修改模擬總線讀函數。 cp2200模塊使用www.icdev.com.cn的，更改pin44連接VCC，即總線復用方式，地址數據復用。 軟件編寫使用avrstudio4.12+sp4+winavr（avrstudio自帶的winavr嵌入方式）。 硬件連接： 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做為主控，只能使用總線模擬方式，其讀寫速度有限，經測試約為雙向11.8kBps(90kbps)。 由于ram有限，僅僅采用了332Bytes的數據緩沖做為收發buffer，超過此長度的以太網包將拋棄。 此工程文件僅僅做為cp220x的一個移植范例，高級tcpip應用代碼因商業緣故不會提供，請勿找我詢問。
