Advanced-control timer (TIM1)

The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on 6

channels. It has complementary PWM outputs with programmable inserted dead times. It

can also be seen as a complete general-purpose timer. The 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 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%).

The counter can be frozen in debug mode.

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

architecture. The advanced control timer can therefore work together with the TIM timers via

the Timer Link feature for synchronization or event chaining.

2.16.2

General-purpose timers (TIM2, TIM3, TIM4, TIM15, TIM16 & TIM17)

There are six synchronizable general-purpose timers embedded in the STM32F100xx

devices (see Table 3 for differences). Each general-purpose timers can be used to generate

PWM outputs, or as simple time base.

TIM2, TIM3, TIM4

STM32F100xx devices feature three synchronizable 4-channels general-purpose timers.

These timers are based on a 16-bit auto-reload up/downcounter and a 16-bit prescaler.

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