Timers and watchdogs

The STM32F038x6 devices include up to five general-purpose timers and an advanced
control timer.
Table 5 compares the features of the different timers.

Advanced-control timer (TIM1)

The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on six
channels. 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%).
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.
3.11.2

General-purpose timers (TIM2, 3, 14, 16, 17)

There are five synchronizable general-purpose timers embedded in the STM32F038x6
devices (see
PWM outputs, or as simple time base.
