__HAL_TIM_ENABLE_OCxFAST macro
Enable fast mode for a given channel.
Syntax
#define __HAL_TIM_ENABLE_OCxFAST(__HANDLE__, __CHANNEL__) \
(((__CHANNEL__) == TIM_CHANNEL_1) ? ((__HANDLE__)->Instance->CCMR1 |= TIM_CCMR1_OC1FE) :\
((__CHANNEL__) == TIM_CHANNEL_2) ? ((__HANDLE__)->Instance->CCMR1 |= TIM_CCMR1_OC2FE) :\
((__CHANNEL__) == TIM_CHANNEL_3) ? ((__HANDLE__)->Instance->CCMR2 |= TIM_CCMR2_OC3FE) :\
((__HANDLE__)->Instance->CCMR2 |= TIM_CCMR2_OC4FE))
Return value
None
Notes
When fast mode is enabled an active edge on the trigger input acts like a compare match on CCx output. Delay to sample the trigger input and to activate CCx output is reduced to 3 clock cycles. Fast mode acts only if the channel is configured in PWM1 or PWM2 mode.
