3.16.1 Advanced timers (TIM1, TIM8)
The advanced-control timers (TIM1 on all devices and TIM8 on STM32F313xx devices) can
each be seen as a three-phase PWM multiplexed on 6 channels. They have complementary
PWM outputs with programmable inserted dead-times. They can also be seen as complete
general-purpose timers. The 4 independent channels can be used for:
● Input capture
● Output compare
● PWM generation (edge or center-aligned modes) with full modulation capability (0-
100%)
● One-pulse mode output
In debug mode, the advanced-control timer counter can be frozen and the PWM outputs
disabled to turn off any power switches driven by these outputs.
Many features are shared with those of the general-purpose TIM timers (described in
Section 3.16.2 using the same architecture, so the advanced-control timers can work
together with the TIM timers via the Timer Link feature for synchronization or event chaining.
