17 Advanced-control timers (TIM1 and TIM8)
This section applies to the whole STM32F4xx family, unless otherwise specified.
17.1 TIM1 and TIM8 introduction
The advanced-control timers (TIM1 and TIM8) consist 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 TIM8) and general-purpose (TIMx) timers are completely
independent, and do not share any resources. They can be synchronized together as
described in Section 17.3.20.
