17.3.2 Input Capture
With the input capture function, the TIM2 can capture the time at which an external event occurs. When
an active edge occurs on the pin of an input capture channel, the TIM2 latches the contents of the counter
into the TIM2 channel registers, T2CHxH:T2CHxL. The polarity of the active edge is programmable. Input
captures can be enabled to generate interrupt requests.
17.3.3 Output Compare
With the output compare function, the TIM2 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 TIM2 can set, clear, or toggle the channel pin. Output compares can be enabled to generate
interrupt requests.
17.3.3.1 Unbuffered Output Compare
Any output compare channel can generate unbuffered output compare pulses as described in
