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 advanced-control timer can work together with the TIMx timers via the Timer Link

feature for synchronization or event chaining.

TIM1 and TIM8 support independent DMA request generation.
