25 Advanced-control timer (TIM1)
In this section, “TIMx” should be understood as “TIM1” since there is only one instance of
this type of timer for the products to which this reference manual applies.
25.1 TIM1 introduction
The advanced-control timer (TIM1) consists of a 16-bit auto-reload counter driven by a
programmable prescaler.
It may be used for a variety of purposes, including measuring the pulse lengths of input
signals (input capture) or generating output waveforms (output compare, PWM,
complementary PWM with dead-time insertion).
Pulse lengths and waveform periods can be modulated from a few microseconds to several
milliseconds using the timer prescaler and the RCC clock controller prescalers.
The advanced-control (TIM1) and general-purpose (TIMy) timers are completely
independent, and do not share any resources. They can be synchronized together as
described in Section 25.3.26: Timer synchronization.
