The TIM clock source can be one of the seven prescaler outputs or the
TIM clock pin, PTE0/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 (TSC) select the TIM clock source.
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.
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
generate TIM CPU interrupt requests.
