15 General-purpose timers (TIM5)
15.1 TIM5 introduction
The general-purpose timer consists of a 32-bit auto-reload counter driven by a
programmable prescaler.
It can be used for a variety of purposes, including measuring the pulse lengths of input
signals (input capture) or generating output waveforms (output compare and PWM).
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.
The timer is completely independent, and do not share any resources.
15.2 TIM5 main features
General-purpose TIMx timer features include:
• 32-bit up, down, up/down auto-reload counter.
• 16-bit programmable prescaler used to divide (also “on the fly”) the counter clock
frequency by any factor between 1 and 65536.
• Up to 4 independent channels for:
– Input capture
– Output compare
– PWM generation (Edge- and Center-aligned modes)
– One-pulse mode output
• Synchronization circuit to control the timer with external signals and to interconnect
several timers.
• 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
