I want to use Timer Capture event to generate DMA requests, how TIM_SelectCCDMA should be called?

TIM_SelectCCDMA(TIMx, ENABLE)?

This will set CCDS bit, but according the reference manual for STM32F303, bit CCDS should be 0.

You want to set one of the CCnDE bits in TIMx_DIER (TIMx DMA/Interrupt enable register) register. I don't know how is this called in Cube.
