TI中文支持网希望通过按键中断唤醒PM3模式下的休眠，但是总是出问题，实现不了。PM2格式通过顶过定时器可以实现，那么可以通过检测一个引脚的电平来实现休眠吗？然后通过按键中断来唤醒休眠，这样可以吗？
据说TI的其他工程里面有这样的例子是吗？是哪个呢？
求大神指点下
Susan Yang：
PM2 是由系统自动调度进入的, 由OSAL调用HAL层的接口实现. PM2 和 PM3都可以通过外部中断来唤醒。

Thank you Susan.我想在问下PM3该怎么进入呢，有例子可以参考吗？谢谢啊

可以参考BLE STACK中Advremote例子，空闲时进入PM3

可以参考之前的讨论帖 http://www.deyisupport.com/question_answer/wireless_connectivity/bluetooth/f/103/t/47722.aspx

cc2541 pm3模式可以移植到cc2540
/*********************************************************************************** Filename: powermode3.c
Description: This software example shows how to properly enter Power Mode 3 and then exit upon Port 0 Interrupt. The SRF05EB LED1 is cleared before entering Power Mode 3, and then set by the Port 0 ISR. Hence, the LED1 is ON in Active Mode and OFF in Power Mode 3.
Note: PM2 and PM3 is not supported on the CC2544.

谢谢，大秦正声。但是在协议站上使用这个好像不行啊，我是通过检测P1_6是否置高来确定是否进入休眠，休眠函数就是使用上面的那种，但是按键中断换不起来啊，而且功耗也是1点几mA，没有达到0点即uA啊，请问这是怎么回事啊？

嗨，Viki ，您说的那个“参考BLE STACK中Advremote例子”在哪里啊，我找了下好像没有啊？

C:\Texas Instruments\BLE-CC254x-1.3.2\Projects\ble\HIDAdvRemote应该是这个
