Timers and watchdogs
The STM32F205xx and STM32F207xx devices include two advanced-control timers, eight
general-purpose timers, two basic timers and two watchdog timers.
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
If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-
100%).
