Hello,
I'm designing a PCB with an interface to an existing STM32769 board.
I would like to use one of the STM32 timer inputs to trigger a timer. When the timer reaches its "compare" value it should trigger a DMA request for an SPI transaction.
According to the reference manual, in order to send a DMA request for SPI, I have to use DMA2. The only timers that can send a request to DMA2 are TIM1 and TIM8.
Now, the only available pin that I have from this 2 timers is a complementary output TIM8_CH1N.
So my question is: can a pin whose alternate function is a complementary timer output also be used as a regular timer input?
Thanks
