Hi,Turning Voltage regulator into low-power mode (LPR) in Stop mode possible only for Category 1 devices as stated in RefMan (6.4.1 p158), but referring on datasheet for L051 family (that's category 3) that's however possible (3.1 p14 & 3.4.3 p21). S...

Thank You TDK, now I know that shadow registers can be updated unconsistently. Now I use BYPSHAD=1 and read twice each register and compare each, up to 10 times to get equal content. Now I testing my code.

Hi! I use STM32L051 RTC and twice during three days at +55 deg.C I have incorrect reading of time. For a 1 minute RTC counts 3599.87 s, at next minute all works as should be - 1 min after spending 1 min. Sometimes I get 62.7 s by 1 minute. Thanks.
