DA14697 Keep RTC in Deep Sleep

Hi Dialog team,
 

Background:

1. LP clock source is from external RC32K

2. Keep RTC working in Deep Sleep.

Issue:

To enter Deep Sleep mode and keep RTC working, try keeping the LP clock working and turning off both RC32K and RCX but the watchdog timer will reset the MCU after 88 seconds even if freeze it before entering DeepSleep.

Is there any possible keep RTC working and disable watchdog in DeepSleep mode?

Thank you
