Timers and watchdogs
The STM32F21x devices include two advanced-control timers, eight general-purpose
timers, two basic timers and two watchdog timers.
All timer counters can be frozen in debug mode.
Table 3 compares the features of the advanced-control, general-purpose and basic timers.

Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
● Input capture
● Output compare
● PWM generation (edge- or center-aligned modes)
● One-pulse mode output
