8.4.1 TIM Counter Prescaler
The TIM clock source can be one of the seven prescaler outputs or the TIM clock pin, TCLK. The
prescaler generates seven clock rates from the internal bus clock. The prescaler select bits, PS[2:0], in
the TIM status and control register select the TIM clock source.
8.4.2 Input Capture
With the input capture function, the TIM can capture the time at which an external event occurs. When an
active edge occurs on the pin of an input capture channel, the TIM latches the contents of the TIM counter
into the TIM channel registers, TCHxH:TCHxL. The polarity of the active edge is programmable. Input
captures can generate TIM CPU interrupt requests.
