==============================================================================
##### How to use this driver #####
==============================================================================
[..]
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
