Advanced-control timers (TIM1, TIM8)

The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators

multiplexed on 6 channels. They have complementary PWM outputs with programmable

inserted dead times. They can also be considered as complete general-purpose timers.

Their 4 independent channels can be used for:

•

Input capture

•

Output compare

•

PWM generation (edge- or center-aligned modes)

•

One-pulse mode output

If configured as standard 16-bit timers, they have the same features as the general-purpose

TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-

100%).

The TIM1 and TIM8 counters can be frozen in debug mode. Many of the advanced-control

timer features are shared with those of the standard TIMx timers which have the same

architecture. The advanced-control timer can therefore work together with the TIMx timers

via the Timer Link feature for synchronization or event chaining.
