Advanced-control timers (TIM1)

15.1

TIM1 introduction

The advanced-control timers (TIM1) consist of a 16-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.
The advanced-control (TIM1) and general-purpose (TIMx) timers are completely
independent, and do not share any resources. They can be synchronized together as
described in
15.2

TIM1 main features

TIM1 timer features include:
●
16-bit up, down, up/down auto-reload counter.
●
16-bit programmable prescaler allowing dividing (also "on the fly") the counter clock
frequency either by any factor between 1 and 65535.
●
Up to 4 independent channels for:
–
–
–
–
●
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.
●
Break input to put the timer's output signals in reset state or in a known state.
●
Interrupt/DMA generation on the following events:
–
–
–
–
–
●
Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
purposes
●
Trigger input for external clock or cycle-by-cycle current management
