找了一下，我这边只有以前测试用的《待机模式》 和《停止模式》的代码。
将就的参考下吧，年代比较久远了。呵呵

* [url=home.php?mod=space&uid=247401]@brief[/url] PWR：待机模式
WFE事件 新来的中断、之前悬起的中断等(比较容易唤醒)
WFI中断
******************************************************************************
*用途：
3.待机模式：可实现系统的最低功耗
进入：
设置CM3系中的SLEEPDEEP位 , PWR_CR中设置PDDS位 , CWUF位
然后执行WFI(等待中断)或WFE(等待事件)指令
唤醒：WKUP引脚的上升沿、RTC闹钟事件、NRST引脚上的外部复位、IWDG复位
唤醒延时：复位阶段时电压调节器的启动
SCB->SCR[4:0] == SEVONPEND,0,SLEEPDEEP,SLEEPONEXIT,0
