Hi Support,
Can SNC work when DA14695 stays at DeepSleep mode?
Is hardware RTC module can be used to wakeup DA14695 from DeepSleep without SNC script?
提前谢谢!

Hi There,
According to datasheet, in Deep sleep mode, nothing is retained, XTAL32K is running (so RTC is on), all domains are off, the system can only be woken up by POR, RTC alarm or a GPIO trigger. This means that the SNC is shut down in deep sleep mode. Please read section 6.4 Power Modes and Rails from the datasheet. Additionally, SNC is under COMMS power domain (PD_COM). Please check Figure 7: Digital Power Domains and Blocks Mapping. Regarding your second question, yes you can use the RTC in order to wake up the DA1469x from deep sleep, but a cold boot will be occurred.
Thanks, PM_Dialog
谢谢!
