 TIM_DMASource : specifies the DMA Request sources. This
parameter can be any combination of the following values:
 TIM_DMA_Update : TIM update Interrupt source
 TIM_DMA_CC1 : TIM Capture Compare 1 DMA source
 TIM_DMA_CC2 : TIM Capture Compare 2 DMA source
 TIM_DMA_CC3 : TIM Capture Compare 3 DMA source
 TIM_DMA_CC4 : TIM Capture Compare 4 DMA source
 TIM_DMA_COM : TIM Commutation DMA source
 TIM_DMA_Trigger : TIM Trigger DMA source
 NewState : new state of the DMA Request sources. This
parameter can be: ENABLE or DISABLE.
Return values
 None.
Notes
 None.
