+     - PWM Mode is used
+     - The TIM1 Update event is used as Trigger Output
+    
+     2/TIM3 and TIM4 are slaves for TIM1,
+     - PWM Mode is used
+     - The ITR0(TIM1) is used as input trigger for both slaves
+     - Gated mode is used, so starts and stops of slaves counters
+       are controlled by the Master trigger output signal(update event).
+
+  o For Low-density, Medium-density, High-density and Connectivity line devices:
+    The TIMxCLK is fixed to 72 MHz, Prescaler = 0 so the TIM1 counter clock is 72 MHz.
+
+    The Master Timer TIM1 is running at:
+    TIM1 frequency = TIM1 counter clock / (TIM1_Period + 1) = 281.250 KHz
+    and the duty cycle is equal to: TIM1_CCR1/(TIM1_ARR + 1) = 50%
+
+    The TIM3 is running at: 
+    (TIM1 frequency)/ ((TIM3 period +1)* (Repetition_Counter+1)) = 18.750 KHz and
+    a duty cycle equal to TIM3_CCR1/(TIM3_ARR + 1) = 33.3%
+
+    The TIM4 is running at:
+    (TIM1 frequency)/ ((TIM4 period +1)* (Repetition_Counter+1)) = 28.125 KHz and
+    a duty cycle equal to TIM4_CCR1/(TIM4_ARR + 1) = 50%
+  
+  o For Low-Density Value line and Medium-Density Value line devices:
+    The TIMxCLK is fixed to 24 MHz, Prescaler = 0 so the TIM1 counter clock is 24 MHz.
+    TIM1 frequency = 93.75 KHz
