Advanced-control timer ( TIM1 / TIM8 )

The advanced-control timer can be seen as a three-phase PWM multiplexed on six chan-

nels. It has complementary PWM outputs with programmable inserted dead times. It can

also be seen as a complete general-purpose timer. The four independent channels can

be used for：

• Input capture

• Output compare

• PWM generation (edge or center-aligned modes)

• One-pulse mode output

If configured as a standard 16-bit timer, it has the same features as the TIMx timer. If

configured as the 16-bit PWM generator, it has full modulation capability (0

∼ 100%).

In debug mode, the counter can be frozen and the PWM output is disabled to cut off the

switches controlled by these outputs.

Many features are shared with those of the standard timers which have the same archi-

tecture. The advanced control timer can therefore work together with the other timers via

the Timer Link feature for synchronization or event chaining.

General-purpose timers (TIMx)

There are 4 synchronizable general-purpose timers ( TIM2、TIM3 、TIM4 、TIM5).

General-purpose timers 32-bit

The timer is based on a 32-bit auto-reload up/downcounter and a 16-bit prescaler. The

feature is 4 independent channels each for input capture/output compare, PWM or one-

pulse mode output.
