In debug mode, the advanced-control timer 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 TIM timers (described in
Section 3.16.2
together with the TIM timers via the Timer Link feature for synchronization or event chaining.
General-purpose timers (TIM2, TIM3, TIM4, TIM15, TIM16, TIM17)
There are up to six synchronizable general-purpose timers embedded in the
STM32F302xx/STM32F303xx (see
can be used to generate PWM outputs, or act as a simple time base.

Basic timers (TIM6, TIM7)
These timers are mainly used for DAC trigger generation. They can also be used as a
generic 16-bit time base.
Independent watchdog (IWDG)
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 40 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free running timer for application timeout
management. It is hardware or software configurable through the option bytes. The counter
can be frozen in debug mode.
TIM2, 3, and TIM4
These are full-featured general-purpose timers:
–
–
These timers all feature 4 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
These three timers general-purpose timers with mid-range features:
They have 16-bit auto-reload upcounters and 16-bit prescalers.
–
–
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.
TIM2 has a 32-bit auto-reload up/downcounter and 32-bit prescaler
TIM3 and 4 have 16-bit auto-reload up/downcounters and 16-bit prescalers.
TIM15 has 2 channels and 1 complementary channel
TIM16 and TIM17 have 1 channel and 1 complementary channel
using the same architecture, so the advanced-control timers can work
