3.19.1 Advanced-control timers (TIM1)
The advanced-control timer (TIM1) can be seen as three-phase PWM generators
multiplexed on 4 independent channels. It has complementary PWM outputs with
programmable inserted dead times. It can also be considered as a complete general-
purpose timer. Its 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, it has the same features as the general-purpose
TIMx timers. If configured as a 16-bit PWM generator, it has 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 supports independent DMA request generation.
