Advanced control timer

The Adv_Timer (Advanced-control Timers) consist of a 32-bit auto-reload counter driven by a programmable prescaler. It may be used for a variety of purposes, including measuring the pulse lengths of input signals (input capture) or generating output waveforms (output compare, PWM, complementary PWM with dead-time insertion). Pulse lengths and waveform periods can be modulated from a few microseconds to several milliseconds using the timer prescaler and the RCC clock controller prescalers.

• 32-bit up, down, up/down auto-reload counter
• 32-bit programmable prescaler allowing dividing (also “on the fly”) the counter clock frequency either by any factor between 1 and 4294967296
• Up to 4 independent channels for:
  • Input Capture,
  • Output Compare,
  • PWM generation (Edge and Center-aligned Mode),
  • One-pulse mode output
• Complementary outputs with programmable dead-time
• Synchronization circuit to control the timer with external signals and to interconnect several timers together
• Repetition counter to update the timer registers only after a given number of cycles of the counter
• 2 break inputs to put the timer’s output signals in a safe user selectable configuration
• Interrupt/DMA generation on the following events:
  • Update: counter overflow/underflow, counter initialization (by software or internal/external trigger),
  • Trigger event (counter start, stop, initialization or count by internal/external trigger),
  • Input capture,
  • Output compare
• Supports incremental (quadrature) encoder and Hall-sensor circuitry for positioning purposes
• Trigger input for external clock or cycle-by-cycle current management
