+                     ##### 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 LL_mDelay and LL_Init1msTick
+          functions
+      (+) Low power mode configuration (SCB register of Cortex-MCU)
+      (+) MPU API to configure and enable regions
+      (+) API to access to MCU info (CPUID register)

+    [..]  This section provides functions allowing to:
+      (+) Initialize the Flash interface the NVIC allocation and initial time base
+          clock configuration.
+      (+) De-initialize common part of the HAL.
+      (+) Configure the time base source to have 1ms time base with a dedicated
+          Tick interrupt priority.
+        (++) SysTick timer is used by default as source of time base, but user
+             can eventually implement his proper time base source (a general purpose
+             timer for example or other time source), keeping in mind that Time base
+             duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
+             handled in milliseconds basis.
+        (++) Time base configuration function (HAL_InitTick ()) is called automatically
+             at the beginning of the program after reset by HAL_Init() or at any time
+             when clock is configured, by HAL_RCC_ClockConfig().
+        (++) Source of time base is configured  to generate interrupts at regular
+             time intervals. Care must be taken if HAL_Delay() is called from a
+             peripheral ISR process, the Tick interrupt line must have higher priority
+            (numerically lower) than the peripheral interrupt. Otherwise the caller
+            ISR process will be blocked.
+       (++) functions affecting time base configurations are declared as __weak
+             to make  override possible  in case of other  implementations in user file.

+    The Cortex M0+ exceptions are managed by CMSIS functions.
+      (#) Enable and Configure the priority of the selected IRQ Channels.
+             The priority can be 0..3.
+
+        -@- Lower priority values gives higher priority.
+        -@- Priority Order:
+            (#@) Lowest priority.
+            (#@) Lowest hardware priority (IRQn position).

+      (#)  Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority()
+
+      (#)  Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ()
+
+      -@-  Negative value of IRQn_Type are not allowed.
+
+    *** How to configure Systick using CORTEX HAL driver ***
+    ========================================================
+    [..]
+    Setup SysTick Timer for time base.
+
+   (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
+       is a CMSIS function that:
+        (++) Configures the SysTick Reload register with value passed as function parameter.
+        (++) Configures the SysTick IRQ priority to the lowest value (0x03).
+        (++) Resets the SysTick Counter register.
+        (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
+        (++) Enables the SysTick Interrupt.
+        (++) Starts the SysTick Counter.
+
+   (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
+       __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
+       HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
+       inside the stm32g0xx_hal_cortex.h file.
+
+   (+) You can change the SysTick IRQ priority by calling the
+       HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
+       call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
+
+   (+) To adjust the SysTick time base, use the following formula:
+
+       Reload Value = SysTick Counter Clock (Hz) x  Desired Time base (s)
+       (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
+       (++) Reload Value should not exceed 0xFFFFFF

+  The DMA Extension HAL driver can be used as follows:
+   (+) Configure the DMAMUX Synchronization Block using HAL_DMAEx_ConfigMuxSync function.
+   (+) Configure the DMAMUX Request Generator Block using HAL_DMAEx_ConfigMuxRequestGenerator function.
+       Functions HAL_DMAEx_EnableMuxRequestGenerator and HAL_DMAEx_DisableMuxRequestGenerator can then be used
+       to respectively enable/disable the request generator.
+
+   (+) To handle the DMAMUX Interrupts, the function  HAL_DMAEx_MUX_IRQHandler should be called from
+       the DMAMUX IRQ handler i.e DMAMUX1_OVR_IRQHandler.
+       As only one interrupt line is available for all DMAMUX channels and request generators , HAL_DMAEx_MUX_IRQHandler should be
+       called with, as parameter, the appropriate DMA handle as many as used DMAs in the user project
+      (exception done if a given DMA is not using the DMAMUX SYNC block neither a request generator)

+  ==============================================================================
+  [..]
+    (+) Each Exti line can be configured within this driver.
+
+    (+) Exti line can be configured in 3 different modes
+        (++) Interrupt
+        (++) Event
+        (++) Both of them
+
+    (+) Configurable Exti lines can be configured with 3 different triggers
+        (++) Rising
+        (++) Falling
+        (++) Both of them
+
+    (+) When set in interrupt mode, configurable Exti lines have two diffenrents
+        interrupt pending registers which allow to distinguish which transition
+        occurs:
+        (++) Rising edge pending interrupt
+        (++) Falling
+
+    (+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
+        be selected through multiplexer.
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+
+    (#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
+        (++) Choose the interrupt line number by setting "Line" member from
+             EXTI_ConfigTypeDef structure.
+        (++) Configure the interrupt and/or event mode using "Mode" member from
+             EXTI_ConfigTypeDef structure.
+        (++) For configurable lines, configure rising and/or falling trigger
+             "Trigger" member from EXTI_ConfigTypeDef structure.
+        (++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
+             member from GPIO_InitTypeDef structure.
+
+    (#) Get current Exti configuration of a dedicated line using
+        HAL_EXTI_GetConfigLine().
+        (++) Provide exiting handle as parameter.
+        (++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
+
+    (#) Clear Exti configuration of a dedicated line using HAL_EXTI_ClearConfigLine().
+        (++) Provide exiting handle as parameter.
+
+    (#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
+        (++) Provide exiting handle as first parameter.
+        (++) Provide which callback will be registered using one value from
+             EXTI_CallbackIDTypeDef.
+        (++) Provide callback function pointer.
+
+    (#) Get interrupt pending bit using HAL_EXTI_GetPending().
+
+    (#) Clear interrupt pending bit using HAL_EXTI_ClearPending().
+
+    (#) Generate software interrupt using HAL_EXTI_GenerateSWI().

+  * @author  MCD Application Team
+  * @brief   FLASH HAL module driver.
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the internal FLASH memory:
+  *           + Program operations functions
+  *           + Memory Control functions
+  *           + Peripheral Errors functions
+  *
+ @verbatim
+  ==============================================================================
+                        ##### FLASH peripheral features #####
+  ==============================================================================
+
+  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
+       to the Flash memory. It implements the erase and program Flash memory operations
+       and the read and write protection mechanisms.
+
+  [..] The Flash memory interface accelerates code execution with a system of instruction
+       prefetch and cache lines.
+
+  [..] The FLASH main features are:
+      (+) Flash memory read operations
+      (+) Flash memory program/erase operations
+      (+) Read / write protections
+      (+) Option bytes programming
+      (+) Prefetch on I-Code
+      (+) 32 cache lines of 4*64 bits on I-Code
+      (+) Error code correction (ECC) : Data in flash are 72-bits word
+          (8 bits added per double word)
+
+                        ##### How to use this driver #####
+ ==============================================================================
+    [..]
+      This driver provides functions and macros to configure and program the FLASH
+      memory of all STM32G0xx devices.
+
+      (#) Flash Memory IO Programming functions:
+           (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
+                HAL_FLASH_Lock() functions
+           (++) Program functions: double word and fast program (full row programming)
+           (++) There are two modes of programming:
+            (+++) Polling mode using HAL_FLASH_Program() function
+            (+++) Interrupt mode using HAL_FLASH_Program_IT() function
+
+      (#) Interrupts and flags management functions:
+           (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
+           (++) Callback functions are called when the flash operations are finished :
+                HAL_FLASH_EndOfOperationCallback() when everything is ok, otherwise
+                HAL_FLASH_OperationErrorCallback()
+           (++) Get error flag status by calling HAL_GetError()
+
+      (#) Option bytes management functions :
+           (++) Lock and Unlock the option bytes using HAL_FLASH_OB_Unlock() and
+                HAL_FLASH_OB_Lock() functions
+           (++) Launch the reload of the option bytes using HAL_FLASH_OB_Launch() function.
+                In this case, a reset is generated
+
+    [..]
+      In addition to these functions, this driver includes a set of macros allowing
+      to handle the following operations:
+       (+) Set the latency
+       (+) Enable/Disable the prefetch buffer
+       (+) Enable/Disable the Instruction cache
+       (+) Reset the Instruction cache
+       (+) Enable/Disable the Flash power-down during low-power run and sleep modes
+       (+) Enable/Disable the Flash interrupts
+       (+) Monitor the Flash flags status

+  ==============================================================================
+                    ##### GPIO Peripheral features #####
+  ==============================================================================
+  [..]
+    (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
+        configured by software in several modes:
+        (++) Input mode
+        (++) Analog mode
+        (++) Output mode
+        (++) Alternate function mode
+        (++) External interrupt/event lines
+
+    (+) During and just after reset, the alternate functions and external interrupt
+        lines are not active and the I/O ports are configured in input floating mode.
+
+    (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
+        activated or not.
+
+    (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
+        type and the IO speed can be selected depending on the VDD value.
+
+    (+) The microcontroller IO pins are connected to onboard peripherals/modules through a
+        multiplexer that allows only one peripheral alternate function (AF) connected
+       to an IO pin at a time. In this way, there can be no conflict between peripherals
+       sharing the same IO pin.
+
+    (+) All ports have external interrupt/event capability. To use external interrupt
+        lines, the port must be configured in input mode. All available GPIO pins are
+        connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
+
+    (+) The external interrupt/event controller consists of up to 28 edge detectors
+        (16 lines are connected to GPIO) for generating event/interrupt requests (each
+        input line can be independently configured to select the type (interrupt or event)
+        and the corresponding trigger event (rising or falling or both). Each line can
+        also be masked independently.
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (#) Enable the GPIO AHB clock using the following function: __HAL_RCC_GPIOx_CLK_ENABLE().
+
+    (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
+        (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
+        (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
+             structure.
+        (++) In case of Output or alternate function mode selection: the speed is
+             configured through "Speed" member from GPIO_InitTypeDef structure.
+        (++) In alternate mode is selection, the alternate function connected to the IO
+             is configured through "Alternate" member from GPIO_InitTypeDef structure.
+        (++) Analog mode is required when a pin is to be used as ADC channel
+             or DAC output.
+        (++) In case of external interrupt/event selection the "Mode" member from
+             GPIO_InitTypeDef structure select the type (interrupt or event) and
+             the corresponding trigger event (rising or falling or both).
+
+    (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
+        mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
+        HAL_NVIC_EnableIRQ().
+
+    (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
+
+    (#) To set/reset the level of a pin configured in output mode use
+        HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
+
+   (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
+
+    (#) During and just after reset, the alternate functions are not
+        active and the GPIO pins are configured in input floating mode (except JTAG
+        pins).
+
+    (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
+        (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
+        priority over the GPIO function.
+
+    (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
+        general purpose PF0 and PF1, respectively, when the HSE oscillator is off.
+        The HSE has priority over the GPIO function.
