Tool/software: Code Composer Studio
Hi! I am working with an MSP430FR5994 and trying to use it in LPM3 with a RTC_C and TA0 for interrupts. I noticed something strange.
The RTC will initialize correctly, but after it goes into LPM3 using __bis_SR_register(LPM3_bits) the RTC registers will reset and the RTC itself will stop running and get stuck at UnixTime 9 (Jan 1st, 1970 00:00:09). Also the timer is fine. It is not being reset like the RTC.
I am not sure what is causing this as the RTC should be able to work till LPM3.5. Also it seemed to work fine without the LPM code. Any suggestions on what could be causing this and how to avoid it would be appreciated! Thank you
