Kojto 158:b23ee177fd68 12 [..]
Kojto 158:b23ee177fd68 13 The LL SYSTEM driver contains a set of generic APIs that can be
Kojto 158:b23ee177fd68 14 used by user:
Kojto 158:b23ee177fd68 15 (+) Some of the FLASH features need to be handled in the SYSTEM file.
Kojto 158:b23ee177fd68 16 (+) Access to DBGCMU registers
Kojto 158:b23ee177fd68 17 (+) Access to SYSCFG registers
