Functional overview

3.25.1

Advanced-control timer (TIM1)

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

channels. Each channel has complementary PWM outputs with programmable inserted

dead-times. Each channel can also be seen as complete general-purpose timers.

The four independent channels can be used for:

•

input capture

•

output compare

•

PWM generation (edge or center-aligned modes) with full modulation capability

(0 - 100 %)

•

one-pulse mode output

In debug mode, the TIM1 counter can be frozen and the PWM outputs disabled to turn off

any power switches driven by these outputs.

Many features are shared with those of the general-purpose timers (described in the next

section) using the same architecture. TIM1 can then work together with TIM2 via the

peripheral interconnect matrix, for synchronization or event chaining.

3.25.2

General-purpose timers (TIM2, TIM16, TIM17)

Each general-purpose timer can be used to generate PWM outputs, or act as a simple time

base.

TIM2 main features:

•

full-featured general-purpose timer

•

four independent channels for input capture/output compare, PWM or one-pulse mode

output

•

counter that can be frozen in debug mode

•

independent DMA request generation, support of quadrature encoders
