Introduction

Timebase Timer (TB)
The timebase timer is based on a 16-bit auto-reload counter and not connected to the I/O
pins. It can be used for software triggering, or to implement the scheduler of a real time
operating system.
Synchronizable Standard Timers (TIM2:0)
The three standard timers are based on a 16-bit auto-reload counter and feature up to 2
input captures and 2 output compares (for external triggering or time base / time out
management). They can work together with the PWM timer via the Timer Link feature for
synchronization or event chaining. In reset state, timer Alternate Function I/Os are
connected to the same
I/O ports in both 64-pin and 100-pin devices. To optimize timer functions in 64-pin devices,
timer Alternate Function I/Os can be connected, or “remapped”, to other I/O ports as
summarized in
a control register.
Table 2. Standard timer alternate function I/Os
Any of the standard timers can be used to generate PWM outputs. One timer (TIM0) is
mapped to a DMA channel.
Motor Control PWM timer (PWM)
The Motor Control PWM Timer (PWM) can be seen as a three-phase PWM multiplexed on 6
channels. The 16-bit PWM generator has full modulation capability (0...100%), edge or
centre-aligned patterns and supports dead-time insertion. It has many features in common
with the standard TIM timers which has the same architecture and it can work together with
the TIM timers via the Timer Link feature for synchronization or event chaining.The PWM
timer is mapped to a DMA channel.
I²C bus
The I²C bus interface can operate in multi-master and slave mode. It can support standard
and fast modes (up to 400KHz).
