Tool/software:

I'm using the SDK example rtc_periodic_alarm_lfosc_standby_LP_MSPM0G3507_nortos_ticlang, which demonstrates the use of Standby0 mode. This mode is working as expected.

However, when I try to use Standby1 mode, the device doesn't wake up. My question is: Is it possible to wake up from Standby1 using an RTC interrupt?

Hi,

I will have the test tomorrow, and give you feedback.

Hi,

The RTCCLK can be sourced from internal LFOSC or the external low frequency crystal oscillator (LFXT).

If you use internal LFLCK, it will be disabled in standby1 mode

If you use external LFXT, RTC will work.

Hi,

I used the rtc_periodic_alarm_lfxt_standby_LP_MSPM0G3507_nortos_ticlang example to configure the RTC with an external LFXT clock. However, the device still doesn't wake up from Standby1 mode.

Hi,

Sorry for incorrect information. I have checked from my side. RTC will be workable when in standby1 mode. But it cannot generate an interrupt to wake up the MCU in standby1 mode. And only TimerG0/8 and GPIO can realize this.

To confirm the RTC is workable in standby mode, you can: enable output frequency .
