basic timers (BSTIM1) are completely independent and do not share any clock sources.

The features are described as follows:

 16-bit auto-reload up-counter

 16-bit programmable Prescaler allows the counter clock frequency to be divided by any

factor between 1 and 65536 (on the fly)

 Up to 2 independent channels

 Input capture

 Output compare

 PWM generation (Edge-aligned and Center-aligned modes)

 One-pulse mode output

 Complementary output programmable dead-time register

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

timers

 The repeat counter is used to update the timing register and only works after the definition

number of the counter period

 Pause input to put timer output signal in reset state or known state

 Interrupt/DMA generation on the following events:

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

internal/external trigger)

 Trigger event (counter start, stop, initialization or count by internal/external trigger)

 Input capture (capture register)

 Output compare (count register paired with compare register)

 Brake signal input

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

4.12 Basic Timer(BSTIM)

The basic timer consists 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). 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.

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

timers (BSTIM) are completely independent and do not share any clock source.

The features are described as follows:

 16-bit auto-reload up-counter
