-    [..]
-      (+) The IWDG can be started by either software or hardware (configurable
-          through option byte).
-      (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
-          thus stays active even if the main clock fails.
-      (+) Once the IWDG is started, the LSI is forced ON and cannot be disabled
-          (LSI cannot be disabled too), and the counter starts counting down from 
-          the reset value of 0xFFF. When it reaches the end of count value (0x000)
-          a system reset is generated.
-      (+) The IWDG counter should be refreshed at regular intervals, otherwise the
-          watchdog generates an MCU reset when the counter reaches 0.          
-      (+) The IWDG is implemented in the VDD voltage domain that is still functional
-          in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
-      (+) IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
-          reset occurs.
-      (+) Min-max timeout value @41KHz (LSI): ~0.1ms / ~25.5s
-          The IWDG timeout may vary due to LSI frequency dispersion. STM32F0x
-          devices provide the capability to measure the LSI frequency (LSI clock
-          connected internally to TIM16 CH1 input capture). The measured value
-          can be used to have an IWDG timeout with an acceptable accuracy.
-          For more information, please refer to the STM32F0x Reference manual.

+  [..]
+    (+) The IWDG can be started by either software or hardware (configurable
+        through option byte).
+
+    (+) The IWDG is clocked by Low-Speed clock (LSI) and thus stays active even
+        if the main clock fails.
+
+    (+) Once the IWDG is started, the LSI is forced ON and both can not be 
+        disabled. The counter starts counting down from the reset value (0xFFF).
+        When it reaches the end of count value (0x000) a reset signal is 
+        generated (IWDG reset).
+
+    (+) Whenever the key value 0x0000 AAAA is written in the IWDG_KR register, 
+        the IWDG_RLR value is reloaded in the counter and the watchdog reset is
+        prevented.
+
+    (+) The IWDG is implemented in the VDD voltage domain that is still functional
+        in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
+        IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
+        reset occurs.
+
+    (+) Debug mode : When the microcontroller enters debug mode (core halted),
+        the IWDG counter either continues to work normally or stops, depending 
+        on DBG_IWDG_STOP configuration bit in DBG module, accessible through
+        __HAL_DBGMCU_FREEZE_IWDG() and __HAL_DBGMCU_UNFREEZE_IWDG() macros

     Once enabled the WWDG generates a system reset on expiry of a programmed
     time period, unless the program refreshes the counter (T[6;0] downcounter)
     before reaching 0x3F value (i.e. a reset is generated when the counter
-    value rolls over from 0x40 to 0x3F). 
-       
+    value rolls over from 0x40 to 0x3F).
+
     (+) An MCU reset is also generated if the counter value is refreshed
-        before the counter has reached the refresh window value. This 
+        before the counter has reached the refresh window value. This
         implies that the counter must be refreshed in a limited window.
+
     (+) Once enabled the WWDG cannot be disabled except by a system reset.
+
     (+) WWDGRST flag in RCC_CSR register informs when a WWDG reset has 
-        occurred (check available with __HAL_RCC_GET_FLAG(RCC_FLAG_WWDGRST)).               
-    (+) The WWDG counter input clock is derived from the APB clock divided 
+        occurred (check available with __HAL_RCC_GET_FLAG(RCC_FLAG_WWDGRST)).
+
+    (+) The WWDG downcounter input clock is derived from the APB clock divided
         by a programmable prescaler.
-    (+) WWDG clock (Hz) = PCLK / (4096 * Prescaler)
-    (+) WWDG timeout (mS) = 1000 * (T[5;0] + 1) / WWDG clock
-        where T[5;0] are the lowest 6 bits of Counter.
+	
+    (+) WWDG downcounter clock (Hz) = PCLK / (4096 * Prescaler)
+
+    (+) WWDG timeout (ms) = (1000 * (T[5;0] + 1)) / (WWDG downcounter clock)
+        where T[5;0] are the lowest 6 bits of downcounter.
+
     (+) WWDG Counter refresh is allowed between the following limits :
-        (++) min time (mS) = 1000 * (Counter-Window) / WWDG clock
-        (++) max time (mS) = 1000 * (Counter-0x40) / WWDG clock
+        (++) min time (ms) = (1000 * (T[5;0] - Window)) / (WWDG downcounter clock)
+        (++) max time (ms) = (1000 * (T[5;0] - 0x40)) / (WWDG downcounter clock)
+
     (+) Min-max timeout value @48 MHz(PCLK): ~85,3us / ~5,46 ms
-   
+	
+    (+) The Early Wakeup Interrupt (EWI) can be used if specific safety 
+        operations or data logging must be performed before the actual reset is
+        generated. When the downcounter reaches the value 0x40, an EWI interrupt
+        is generated and the corresponding interrupt service routine (ISR) can 
+        be used to trigger specific actions (such as communications or data 
+        logging), before resetting the device.
+        In some applications, the EWI interrupt can be used to manage a software
+        system check and/or system recovery/graceful degradation, without 
+        generating a WWDG reset. In this case, the corresponding interrupt 
+        service routine (ISR) should reload the WWDG counter to avoid the WWDG 
+        reset, then trigger the required actions.
+        Note:When the EWI interrupt cannot be served, e.g. due to a system lock 
+        in a higher priority task, the WWDG reset will eventually be generated.
+
+    (+) Debug mode : When the microcontroller enters debug mode (core halted),
+        the WWDG counter either continues to work normally or stops, depending 
+        on DBG_WWDG_STOP configuration bit in DBG module, accessible through
+        __HAL_DBGMCU_FREEZE_WWDG() and __HAL_DBGMCU_UNFREEZE_WWDG() macros
+
                      ##### How to use this driver #####
- ===============================================================================
-      [..]
-      (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
-      (+) Set the WWDG prescaler, refresh window and counter value 
-          using HAL_WWDG_Init() function.
-      (+) Start the WWDG using HAL_WWDG_Start() function.
-          When the WWDG is enabled the counter value should be configured to 
-          a value greater than 0x40 to prevent generating an immediate reset.
-      (+) Optionally you can enable the Early Wakeup Interrupt (EWI) which is 
-          generated when the counter reaches 0x40, and then start the WWDG using
-        HAL_WWDG_Start_IT(). At EWI HAL_WWDG_WakeupCallback() is executed and user can 
-        add his own code by customization of function pointer HAL_WWDG_WakeupCallback().
-          Once enabled, EWI interrupt cannot be disabled except by a system reset.          
+  ==============================================================================
+  [..]
+    (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
+
+    (+) Set the WWDG prescaler, refresh window, counter value and Early Wakeup 
+        Interrupt mode using using HAL_WWDG_Init() function.
+        This enables WWDG peripheral and the downcounter starts downcounting 
+        from given counter value.
+        Init function can be called again to modify all watchdog parameters, 
+        however if EWI mode has been set once, it can't be clear until next 
+        reset.
+
     (+) The application program must refresh the WWDG counter at regular
         intervals during normal operation to prevent an MCU reset using
-          HAL_WWDG_Refresh() function. This operation must occur only when
-          the counter is lower than the refresh window value already programmed.
-  
+        HAL_WWDG_Refresh() function. This operation must occur only when
+        the counter is lower than the window value already programmed.
+
+    (+) if Early Wakeup Interrupt mode is enable an interrupt is generated when 
+        the counter reaches 0x40. User can add his own code in weak function 
+        HAL_WWDG_EarlyWakeupCallback().

+  * @note   These ADC registers are data registers:

+  *           applications.
+  *           How to use this low power mode:
+  *           - Do not use with interruption or DMA since these modes
+  *             have to clear immediately the EOC flag to free the
+  *             IRQ vector sequencer.
+  *           - Do use with polling: 1. Start conversion,

+  *             conversion  to ensure that conversion is completed and
+  *             retrieve ADC conversion data. This will trig another
+  *             ADC conversion start.
+  *         - ADC low power mode "auto power-off" (feature available on

+  ==============================================================================
+    [..]  
+      A delay between an RCC peripheral clock enable and the effective peripheral 
+      enabling should be taken into account in order to manage the peripheral read/write 
+      from/to registers.
+      (+) This delay depends on the peripheral mapping.
+        (++) AHB & APB peripherals, 1 dummy read is necessary
+
+    [..]  
+      Workarounds:
+      (#) For AHB & APB peripherals, a dummy read to the peripheral register has been
+          inserted in each LL_{BUS}_GRP{x}_EnableClock() function.
