Functional overview

3.20

Timers and watchdogs

The devices embed one advanced-control timer, seven general-purpose timers and two

watchdog timers.

All timer counters can be frozen in debug mode.

Table 4 compares the features of the advanced-control and general-purpose timers.

3.20.1

Advanced-control timers (TIM1)

The advanced-control timer (TIM1) can be seen as three-phase PWM generators

multiplexed on 4 independent channels. It has complementary PWM outputs with

programmable inserted dead times. It can also be considered as a complete general-

purpose timer. Its 4 independent channels can be used for:

•

Input capture

•

Output compare

•

PWM generation (edge- or center-aligned modes)

•

One-pulse mode output
