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%).

The counter can be frozen in debug mode.

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

architecture. 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 (TIM2, 3, 14, 16, 17)

There are five synchronizable general-purpose timers embedded in the STM32F048x6

devices (see Table 6 for differences). Each general-purpose timer can be used to generate

PWM outputs, or as simple time base.

TIM2, TIM3

STM32F048x6 devices feature two synchronizable 4-channel general-purpose timers. TIM2

is based on a 32-bit auto-reload up/downcounter and a 16-bit prescaler. TIM3 is 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-pulse mode output. This

gives up to 12 input captures/output compares/PWMs on the largest packages.

The TIM2 and TIM3 general-purpose timers can work together or with the TIM1 advanced-

control timer via the Timer Link feature for synchronization or event chaining.

TIM2 and TIM3 both have independent DMA request generation.

These timers are capable of handling quadrature (incremental) encoder signals and the

digital outputs from 1 to 3 hall-effect sensors.

Their counters can be frozen in debug mode.

TIM14

This timer is based on a 16-bit auto-reload upcounter and a 16-bit prescaler.

TIM14 features one single channel for input capture/output compare, PWM or one-pulse

mode output.

Its counter can be frozen in debug mode.

TIM16 and TIM17

Both timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.

They each have a single channel for input capture/output compare, PWM or one-pulse

mode output.
