   2          /*
   3          Philips 51LPC是采用兩倍速80C51內核的低成本,低功耗,低功耗,低EMI,高抗干擾性及 
   4          內建電源Brownout,模擬功能,UART,I2C和片內RC振蕩器的新一代單片機.該系列目前已 
   5          包括P87LPC760/1/2/4/7/8/9共六個型號.51LPC提供高速和低速的晶振和RC振蕩方式, 
   6          可編程選擇具有較寬的操作電壓范圍2.7-6.0V,可編程I/O口線輸出模式選擇,可選擇 
   7          施密特觸發輸入,LED驅動輸出有內部看門狗定時器及提供掉電檢測模擬功能.最大限 
   8          度地減少了外部元件的使用.這些特性和改進的C51結構結合在一起使得在設計高集成度 
   9          低成本和低功耗控制電路時具有更多的選擇.該系列主要用于對系統成本有嚴格要求的低 
  10          功耗應用領域.
