Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger generation. They can also be used as a
generic 16-bit time base.
Independent watchdog
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.
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from the
main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.
SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
down counter. It features:

one-pulse mode output. This gives up to 16 input captures / output compares / PWMs
on the largest packages.
Their counter can be frozen in debug mode. Any of the general-purpose timers can be
used to generate PWM outputs. They all 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.
TIM10, TIM11 and TIM9
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10 and TIM11 feature one independent channel, whereas TIM9 has two
independent channels for input capture/output compare, PWM or one-pulse mode
output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5 full-featured
general-purpose timers. They can also be used as simple time bases.
TIM13, TIM14 and TIM12
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM13 and TIM14 feature one independent channel, whereas TIM12 has two
independent channels for input capture/output compare, PWM or one-pulse mode
output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5 full-featured
general-purpose timers. They can also be used as simple time bases.
A 24-bit down counter
Autoreload capability
Maskable system interrupt generation when the counter reaches 0.
