Preprocessor Macro calculation

Hi, I have a question about preprocessor C. When I define macros like:#define CON_A 10 #define CON_B 5.6 #define CON_C 20.896 #define MY_MACRO (((10* CON_A)/CON_C)*CON_B)The last one is precalculated by the compiler or is just plain replaced as it...

What is the correct procedure to recover an STM32L4x that has been put in Shutdown and experiences a brown out or POR. it shows the correct flags after reset, but the same flags appear after subsequent Shutdown periods.

This is the sequence of events:Enter Shutdown with RTC Wake up timer enabled (5 seconds)Brown out, remove and restore powerPOR Reset occurs, correct PWR->CSR = 0x0C000600Clear CSR flags by writing 1 to RMVF in CSRRead CSR flags and confirm they are c...
