3.11.5

3.11.6

The TIM15, TIM16 and TIM17 timers can work together, and TIM15 can also operate

withTIM1 via the Timer Link feature for synchronization or event chaining.

TIM15 can be synchronized with TIM16 and TIM17.

TIM15, TIM16 and TIM17 have a complementary output with dead-time generation and

independent DMA request generation.

Their counters can be frozen in debug mode.

Basic timers TIM6 and TIM7

These timers can be used as a generic 16-bit time base.

Independent watchdog (IWDG)

The independent watchdog is based on an 8-bit prescaler and 12-bit downcounter with

user-defined refresh window. 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.

System window watchdog (WWDG)

The system 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 APB clock (PCLK). 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:

• A 24-bit down counter

• Autoreload capability

• Maskable system interrupt generation when the counter reaches 0

• Programmable clock source (HCLK or HCLK/8)
