3.22.1

Advanced-control timers (TIM1, TIM8)

The advanced-control timers (TIM1/8) can be seen as three-phase PWM generator

multiplexed on 4 independent 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 a 16-bit PWM generator, they have full modulation capability

(0-100%).

The advanced-control timers 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.

3.22.2

General-purpose timers (TIMx)

There are elven synchronizable general-purpose timers embedded in the STM32F413xG/H

(see Table 5 for differences).

•

TIM2, TIM3, TIM4, TIM5

The STM32F413xG/H devices include 4 full-featured general-purpose timers: TIM2.

TIM3, TIM4 and TIM5. TIM2 and TIM5 timers are based on a 32-bit auto-reload

up/downcounter and a 16-bit prescaler while TIM3 and TIM4 timers are based on a 16-

bit auto-reload up/downcounter plus a 16-bit prescaler. They all features four
