Timers and watchdogs
The STM32F051xx devices include up to six general-purpose timers, one basic timer and
an advanced control timer.
Table 7
compares the features of the different timers.
3.14.1
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.
