* @brief Selects the TIM Output Compare Mode.
* @note This function does NOT disable the selected channel before changing the Output
* Compare Mode. If needed, user has to enable this channel using
* TIM_CCxCmd() and TIM_CCxNCmd() functions.
* @param TIMx: where x can be 1, 2, 3, 4, 8, 15, 16 or 17 to select the TIM peripheral.
* @param TIM_Channel: specifies the TIM Channel
* This parameter can be one of the following values:
* @arg TIM_Channel_1: TIM Channel 1
* @arg TIM_Channel_2: TIM Channel 2
* @arg TIM_Channel_3: TIM Channel 3
* @arg TIM_Channel_4: TIM Channel 4
* @param TIM_OCMode: specifies the TIM Output Compare Mode.
* This parameter can be one of the following values:
* @arg TIM_OCMode_Timing
* @arg TIM_OCMode_Active
* @arg TIM_OCMode_Toggle
* @arg TIM_OCMode_PWM1
* @arg TIM_OCMode_PWM2
* @arg TIM_ForcedAction_Active
