MSP432P401R进入deepsleep（LPM3）模式后，想实现按键短按闪灯与长按退出deepsleep。请问如何在deepsleep下准确识别按键长按短按呢？谢谢
很抱歉之前没有仔细看您的问题。 LPM3模式下最大的frequency是32.768KHz。只有看门狗和RTC是可以工作的。若是您操作IO口的话，会使芯片唤醒。
In MSP432P401R and MSP432P401M devices, LPM3 mode restricts maximum frequency of device operation to 32.768 kHz. Only RTC and WDT modules are functional from the low-frequency clock sources (LFXT, REFO, and VLO) while in LPM3. All other peripherals are disabled and high-frequency clock sources are turned off in LPM3.
关于唤醒，您可以看一下 Table 8-10. Wake-up Sources from Low-Power Modes for MSP432P401R and MSP432P401M
