==============================================================================
  [..]
  The LL SYSTEM driver contains a set of generic APIs that can be
  used by user:
    (+) Some of the FLASH features need to be handled in the SYSTEM file.
    (+) Access to DBGCMU registers
    (+) Access to SYSCFG registers
    (+) Access to VREFBUF registers
