8.29 Timers (TIMx)

There are two timer peripherals in these devices support that following key features: TIMGx (general-purpose timer) and TIMAx (advanced timer). TIMGx is a subset of TIMAx, which means these timers share many common features that are compatible in software. For specific configuration, see Table 8-11:

Specific features for the general-purpose timer (TIMGx) include:

  • 16-bit and 32-bit timers with up, down or up-down counting modes, with repeat-reload mode
  • Selectable and configurable clock source
  • 8-bit programmable prescaler to divide the counter clock frequency
  • Two independent CC channels for
    • Output compare
    • Input capture
    • PWM output
    • One-shot mode
  • Support quadrature encoder interface (QEI) for positioning and movement sensing available in TIMG8
  • Support synchronization and cross trigger among different TIMx instances in the same power domain
  • Support interrupt/DMA trigger generation and cross peripherals (such as ADC) trigger capability
  • Cross trigger event logic for Hall sensor inputs (TIMG8)

Specific features for the advanced timer (TIMAx) include:

  • 16-bit timer with up, down or up-down counting modes, with repeat-reload mode
  • Selectable and configurable clock source
  • 8-bit programmable prescaler to divide the counter clock frequency
  • Repeat counter to generate an interrupt or event only after a given number of cycles of the counter
  • Up to four independent CC channels for
    • Output compare
    • Input capture
    • PWM output
    • One-shot mode
  • Two additional capture/compare channels for internal events (CC4/CC5)
  • Shadow register for load and CC register available in TIMA0
  • Complementary output PWM
  • Asymmetric PWM with programmable dead band insertion
  • Fault handling mechanism to ensure the output signals in a safe user-defined state when a fault condition is encountered
  • Support synchronization and cross trigger among different TIMx instances in the same power domain
  • Support interrupt and DMA trigger generation and cross peripherals (such as ADC) trigger capability
  • Two additional capture/compare channels for internal events
