I have set up a slave timer that starts counting when the master timer is enabled.
I want to know if the slave starts counting when the master timer receives a valid edge (my configuration is count on the rising edge), or does the slave counter start counting as soon as the master is enabled and the slave receives a valid edge (clocked much faster than master)?
The picture below should help illustrate, I want to know if A) or B) is true. The slave also counts on rising edges.
Technical details: I am using an STM32F072RB, the master timer is clocked externally from a comparator, the master is set up to trigger on Enable, and the slave timer is configured in Trigger mode.
If scenario B) is true (as I suspect), how can I achieve scenario A)?
