STM32WB55 doesn't remain in STANDBY mode

Hello,I'm trying to put the STM32WB55 into standby mode and eventually wake it up using wakeup pin 1 (PA0), but it wakes up directly after the HAL_PWR_EnterSTANDBYMode() is executed. After that, I checked the PWR->SR1 and it had BLEWUF bit set, but I...

Hello, what are the constraints when reprogramming the ARR register in the LPTIM peripheral? E.g. does the counter need to be stopped, or can it be running? Does the ARRM interrupt get triggered only if CNT==ARR, or also for CNT>ARR?

I could not find a definite answer on the STM32WBx5 reference manual.I am setting the LPTIM to generate a periodic interrupt by configuring the ARR register, say to 1 millisecond period. Occasionally, I need to reprogram the ARR with a longer period,...
