==============================================================================
|
||||
##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
The LL CORTEX driver contains a set of generic APIs that can be
|
||||
used by user:
|
||||
(+) SYSTICK configuration used by @ref LL_mDelay and @ref LL_Init1msTick
|
||||
functions
|
||||
(+) Low power mode configuration (SCB register of Cortex-MCU)
|
||||
(+) MPU API to configure and enable regions
|
||||
(MPU services provided only on some devices)
|
||||
(+) API to access to MCU info (CPUID register)
|
||||
(+) API to enable fault handler (SHCSR accesses)
|
||||
|
||||

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
