   10   This represents STM32 Factory-programmed read only non-volatile area: locked
   11   flash, OTP, read-only HW regs... This contains various information such as:
   12   analog calibration data for temperature sensor (e.g. TS_CAL1, TS_CAL2),
   13   internal vref (VREFIN_CAL), unique device ID...

   38           and non-secure worlds can access. It is needed when, by default, the
   39           related area can only be reached by the secure world.
