18.3.1 TIM2 Counter Prescaler
The TIM2 clock source can be one of the seven prescaler outputs or the TIM2 clock pin, T2CH0. The
prescaler generates seven clock rates from the internal bus clock. The prescaler select bits, PS[2:0], in
the TIM2 status and control register select the TIM2 clock source.
