+     - The TIM1 Enable event is used as Trigger Output 
+
+    2/TIM1 is configured as Slave Timer for an external Trigger connected
+     to TIM1 TI2 pin (TIM1 CH2 configured as input pin):
+     - The TIM1 TI2FP2 is used as Trigger Input
+     - Rising edge is used to start and stop the TIM1: Gated Mode.
+
+    3/TIM3 is slave for TIM1 and Master for TIM4,
+     - Toggle Mode is used
+     - The ITR1(TIM1) is used as input trigger 
+     - Gated mode is used, so start and stop of slave counter
+       are controlled by the Master trigger output signal(TIM1 enable event).
+     - The TIM3 enable event is used as Trigger Output. 
+
+    4/TIM4 is slave for TIM3,
+     - Toggle Mode is used
+     - The ITR2(TIM3) is used as input trigger
+     - Gated mode is used, so start and stop of slave counter
+       are controlled by the Master trigger output signal(TIM3 enable event).

+      The TIMxCLK is fixed to 72 MHZ, the Prescaler is equal to 2 so the TIMx clock 
+      counter is equal to 24 MHz.
+      The Three Timers are running at: 
+      TIMx frequency = TIMx clock counter/ 2*(TIMx_Period + 1) = 162.1 KHz.
+
+    * For Low-Density Value line and Medium-Density Value line devices:
+      The TIMxCLK is fixed to 24 MHz, the Prescaler is equal to 2 so the TIMx clock 
+      counter is equal to 8 MHz.
+      TIMx frequency = TIMx clock counter/ 2*(TIMx_Period + 1) = 54 KHz.
+
+    The starts and stops of the TIM1 counters are controlled by the 
+    external trigger.
+    The TIM3 starts and stops are controlled by the TIM1, and the TIM4 
+    starts and stops are controlled by the TIM3.
