dead-time insertion).

Pulse widths and waveform periods can be modulated from a few microseconds to several milliseconds

using the timer Prescaler and the RCC clock controller Prescaler.

The advanced-control timers (ADTIM) and general-purpose timers (GPTIMA, GPTIMB, GPTIMC) are

completely independent and do not share any resources. They can be synchronized together as well.

The features are as follows:

 16-bit up, down, up/down auto-reload counter.

 16-bit programmable Prescaler allowing dividing (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 Mode)

 One-pulse mode output

 Synchronization circuit can control the timer with external signals and interconnect several

timers.

 Interrupt/DMA request is generated when the following events occur:

 Update: counter overflow/underflow, counter initialization (by software or

internal/external trigger)

 Trigger events (counter start, stop, initialization or count by internal trigger)

 Input capture (capture register)

 Output compare (count register paired with compare register)

 Supports incremental (quadrature) encoder and Hall sensor circuits for positioning

purposes.

 Trigger input for an external clock or cycle-by-cycle current management

4.11 General-Purpose Timer(GPTIMC)

The general-purpose timer (GPTIMC) consists of a 16-bit auto-reload counter driven by a programmable

Prescaler.

It may also be used for multiple 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 by

using the timer Prescaler and the APB clock controller Prescaler.
