TIM_CCxNChannelCmd()

static void TIM_CCxNChannelCmd ( TIM_TypeDef *  TIMx, uint32_t  Channel, uint32_t  ChannelNState  )

static

Enables or disables the TIM Capture Compare Channel xN.

Parameters

TIMx	to select the TIM peripheral
Channel	specifies the TIM Channel This parameter can be one of the following values: TIM_CHANNEL_1: TIM Channel 1 TIM_CHANNEL_2: TIM Channel 2 TIM_CHANNEL_3: TIM Channel 3
ChannelNState	specifies the TIM Channel CCxNE bit new state. This parameter can be: TIM_CCxN_ENABLE or TIM_CCxN_Disable.

Return values

None
