STM32L4 LSE CSS

Question asked by yaman.omer.002 on May 4, 2017

Hello,

I'm using STM32L443. I use LSE for RTC and i use LSE for MSI auto calibration. I use a battery on VBAT pin. When i accidentally touched one of the clock pin i saw that there happens an error. The error sets LSECSSD flag in BDCR. This flag keeps being set even if i power down the microcontroller. I can clear LSECSSD flag only by setting BDRST bit in BDCR. After this step how can i recover System Clock?

Regards;

Ömer
