There are two timer peripherals in these devices
support that following key features: TIMBx (basic timer), 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 8-17:
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 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
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 make sure 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
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 bus clock
- 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
