The maximum timer clock depends on RCC settings. 2. only compare channel. 3. 16 MHz bus clock when supplied by the backup regulator (LP-Stop1/2, LPLV-Stop1/2 or Standby1). 4. 32 kHz timer clock in autonomous mode (Stop1/2, LP-Stop1/2, LPLV-Stop1/2 or Standby1). 3.48.1 Advanced-control timers (TIM1/8/20) The advanced-control timers can be seen as three-phase PWM generators multiplexed on six channels. They have complementary PWM outputs with programmable inserted dead times. They can also be considered as complete general-purpose timers. Their four 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, the advanced-control timers have the same features as the general ‑purpose timers. If configured as 16-bit PWM generators, they have full modulation capability (0 to 100%). The advanced-control timers can work together with general-purpose timers via the timer link feature for synchronization or event chaining. TIM1, TIM8 and TIM20 support independent DMA request generation. STM32MP251C/F STM32MP253C/F STM32MP255C/F STM32MP257C/F Functional overview DS14284 - Rev 3 page 36/241 |
