This code below seems to work. (You'll have to translate the mnemonics to suite your own tool chain.)

g_pRCC->APB1ENR |= TIM2EN;

g_pTIM2->ARR = 0XFFFF;

g_pTIM2->CR1 = TIM_ARPE;

g_pTIM2->CR2 = TIM_MMS1;

g_pTIM2->CR1 |= TIM_CEN;

g_pRCC->APB1ENR |= TIM3EN;

g_pTIM3->ARR = 0XFFFF;

g_pTIM3->CR1 = TIM_ARPE;

g_pTIM3->SMCR = TIM_TS0 | TIM_SMS2 | TIM_SMS1 | TIM_SMS0;

g_pTIM3->CR1 |= TIM_CEN;
