No need to count anything. Just set TIM3 to period 16x that of TIM2 and start them simultaneously using hardware sync.

SOME OF THE ADVANCED TIMERS HAVE A REPETITION COUNT WHICH CAN ​BE FIRED IN ONE SHOT MODE TO GET A SPECIFIC NUMBER OF PULSES. OTHERWISE YOU'RE GOING TO NEED TO COUNT UPDATE INTERRUPTS OR COUNT WITH AN ADDITIONAL TIMER.
