The timer peripherals in these devices
support the following key features, for specific configuration see Table 5-2:
Specific features for the
general-purpose timer (TIMGx) include:
- 16-bit up, down, up-down or
down-up counter, with repeat-reload mode
- 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
- Support quadrature encoder
interface (QEI) for positioning and movement sensing
- 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
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
- 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
