Timer Interface Module (TIM)
14.3.2 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 counter into
the TIM channel registers, TCHxH:TCHxL. The polarity of the active edge is programmable. Input
captures can be enabled to generate interrupt requests.
14.3.3 Output Compare
With the output compare function, the TIM can generate a periodic pulse with a programmable polarity,
duration, and frequency. When the counter reaches the value in the registers of an output compare
channel, the TIM can set, clear, or toggle the channel pin. Output compares can be enabled to generate
interrupt requests.
