hello All

I have question about internal trigger connection.

I use stm32f405 and accordingly document RM0090 (reference manual) table 100 page 660 the TIM12 can be slave of the TIM14.

But TIM14 does not have TIM_CR2 register which contains MMS(Master Mode Selection) bits to select the the source of synchronization (Update or other).

So how to join two timers TIM14 and TIM12 as master slave couple

Thanks .

It's the OC signal in TIM14.

Always get the latest RM - it's Table 101 on page 675 in the current rev.13 of RM0090.
