##### 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
|
