Iam using the following code snippet for checking sram content retension in standby mode but unable to achieve the same. The var value is always getting printed as 60 after wakeup. Iam using STM32Cube IDE with STM32L412RB Nucleo Board:#define BITBAND...

I wanted to write the above mentioned logic to SRAM for checking data retension . Could you please help me to achieve this Iam unable to get any reference for this
