实现低功耗的时候,设备由PM3自动跳回PM2,请问是什么引起的?

我按照网上的教程来实现低功耗

1.打开POWER_SAVING

2.-DRFD_RCVC_ALWAYS_ON=FALSE  

-DPOLL_RATE=0 

-DQUEUED_POLL_RATE=0  

-DRESPONSE_POLL_RATE=0      

3.将key改为中断模式

4.设置为电池供电

在仿真调试中,跟踪  halPwrMgtMode = (timeout == 0) ? HAL_SLEEP_DEEP : HAL_SLEEP_TIMER;发现halPwrMgtMode 一开始为0x03,几次轮训之后就变回0x02,请问这是什么原因?
