IS there anyway to without reset rtc1 and work at low power consumption？

[jenkey.zhu]

Wakeup from system off (not WFE) )will cause a system reset and hence will reset almost all of the peripherals (exceptions are RAM and few registers). RTC will also be rest on wakeup from system off.

my question is: IS there anyway to without reset rtc1 and work at low power consumption（nrf52832）？

Hi,

The answer to this depends on your definition of "low power consumption". As you say, wakeup from system off mode will cause a reset, and most peripherals will be reset. All clock sources will also be shutdown when entering system off mode, stopping all your timers/RTC.

You can still enter system on mode, with RTC still running. System on mode has a base current consumption of 1.2 µA, compared to 0.3 µA for system off mode. In most applications, this is still considered low power. If you requre lower power than this, you might have to consider using an external low power RTC together with system off mode.

Best regards,
