8.27 Timers (TIMx)

There are three types of timer peripherals in these devices support that following key features: TIMGx (general-purpose timer), TIMAx (advanced timer), and TIMBx (basic timer). TIMGx is a subset of TIMAx, which means common features between timer instances are software compatible. For specific configurations, see Table 8-16:

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

  • 16-/32-bit up, down, up-down or down-up counter, with repeat-reload mode
  • Selectable and configurable clock source
  • 8-bit programmable prescaler to divide the counter clock frequency
  • Two independent channels for
    • Output compare
    • Input capture
    • PWM output
    • One-shot mode
  • Shadow CC register available in TIMG6, TIMG7
  • Shadow register for load available in TIMG6, TIMG7
  • Support synchronization and cross trigger among different TIMx instances
  • Support interrupt/DMA trigger generation and cross peripherals (such as ADC) trigger capability

Specific features for the advanced timer (TIMAx) include:

  • 16-bit down or up-down counter, 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 channels for
    • Output compare
    • Input capture
    • PWM output
    • One-shot mode
  • Shadow register for load and CC register available
  • Complementary output PWM with programmable dead band insertion
  • Asymmetric PWM
  • Configurable fault handling mechanism for
    • Fast PWM responses (<40ns) to external fault inputs or comparator events
    • Outputting signals in a safe user-defined state when a latched fault condition has occurred
  • Support synchronization and cross trigger among different TIMx instances
  • Support interrupt and DMA trigger generation and cross peripherals (such as ADC) trigger capability
  • Two additional capture/compare channels for internal events

Specific features for the basic software timer (TIMBx) include:

  • Support for a counter array containing 4 counters
  • Each counter is a 16 bit counter
  • Clocked by the PD0 bus clock (ULPCLK)
  • Ability to concatenate 2 or more counters to create longer time durations
  • Ability to measure timing properties of external events
    • Duration between 2 pulses on an event
    • Counting the number of events
    • Ability to start/stop the counter based on external events or internal events
