本程序简单的示范了如何令AVR ATMEGA16进入睡眠状态及唤醒

　　　　电源管理及睡眠模式的介绍

　　　　进入最低耗电的掉电模式

　　　　关闭各种模块

　　　　外部中断唤醒



M16掉电模式的耗电情况(看门狗关闭),时钟为内部RC 1MHz

0.9uA@Vcc=5.0V [手册的图表约为1.1uA]

0.3uA@Vcc=3.3V [手册的图表约为0.4uA]

//测量的数字万用表是FLUKE 15B,分辨率0.1uA



这个程序需要MCU进入休眠状态，为实现最低功耗，JTAG接口会被关闭，只能通过LED的变化来观察程序的运行。

这个实验里面，用STK500(AVRISP) ISP下载线来烧录更方便。



熔丝位设置

1 关断BOD功能 BODEN=1

2 如果用ISP方式烧录，就可以完全关闭JTAG口了 OCEEN=1，JTAGEN=1
