One-pulse mode output

In Debug mode, the advanced-control timer counter can be frozen and the PWM outputs disabled in order to turn

off any power switches driven by these outputs.

Many features are shared with the general-purpose TIMx timers (described in the next section) using the same

architecture, so the advanced-control timers can work together with the TIMx timers via the Timer Link feature for

synchronization or event chaining.

3.30.2

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

There are up to six synchronizable general-purpose timers embedded in the STM32U375xx devices (see

Table 12. Timer feature comparison for differences). Each general-purpose timer can be used to generate PWM

outputs, or act as a simple time base.

•

TIM2, TIM3, and TIM4

They are full-featured general-purpose timers with 32-bit autoreload up/downcounter and 16-bit prescaler.

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

output. They can work together, or with the other general-purpose timers via the Timer Link feature for

synchronization or event chaining.

The counters can be frozen in Debug mode.

All have independent DMA request generation and support quadrature encoders.

•

TIM15, 16, and 17

They are general-purpose timers with mid-range features.

They have 16-bit autoreload upcounters and 16-bit prescalers.

•

TIM15 has two channels and one complementary channel

•

TIM16 and TIM17 have one channel and one complementary channel

All channels can be used for input capture/output compare, PWM, or one-pulse mode output.

The timers can work together via the Timer Link feature for synchronization or event chaining. The timers have

independent DMA request generation.

The counters can be frozen in Debug mode.

3.30.3

Basic timers (TIM6 and TIM7)

The basic timers TIM6 and TIM7 consist of a 16-bit auto-reload counter driven by a programmable prescaler.

They may be used as generic timers for time-base generation. The basic timer can also be used for triggering the

digital-to-analog converter. This is done with the trigger output of the timer.

3.30.4

Low-power timers (LPTIM1, LPTIM2, LPTIM3, LPTIM4)

The devices embed four low-power timers. Due to its diversity of clock sources, the LPTIM is able to keep running

in all power modes except for Standby mode. They are able to wake up the system from Stop mode.

LPTIM1, LPTIM3, and LPTIM4 are active in Stop 0, Stop 1 and Stop 2 modes.

LPTIM2 is active in Stop 0 and Stop 1 mode.

The low-power timer supports the following features:

•

16-bit up counter with 16-bit autoreload register

•

3-bit prescaler with eight possible dividing factors (1, 2, 4, 8, 16, 32, 64, 128)

•

Selectable clock

–

Internal clock sources: configurable internal clock source (see Section 3.11: Reset and clock

controller (RCC) )

–

External clock source over LPTIM input (working with no LP oscillator running, used by Pulse

Counter application)

•

16-bit ARR autoreload register

•

16-bit capture/compare register

•

Continuous/One-shot mode

•

Selectable software/hardware input trigger

•

Programmable digital glitch filter

•

Configurable output: pulse, PWM
