can also be seen as a complete general-purpose timer. The 4 independent channels can be
used for
Input capture
Output compare
PWM generation (edge- or center-aligned modes)
One-pulse mode output
If configured as a general-purpose 16-bit timer, it has the same features as the TIMx timer. If
configured as the 16-bit PWM generator, it has full modulation capability (0-100%).
In debug mode, the advanced-control timer counter can be frozen and the PWM outputs
disabled to turn off any power switch driven by these outputs.
Many features are shared with those of the general-purpose TIM timers which have the
same architecture. The advanced-control timer can therefore work together with the TIM
timers via the Timer Link feature for synchronization or event chaining.
General-purpose timers (TIMx)
There are up to three synchronizable general-purpose timers embedded in the
STM32F103xx performance line devices. These timers are based on a 16-bit auto-reload
up/down counter, a 16-bit prescaler and feature 4 independent channels each for input
capture/output compare, PWM or one-pulse mode output. This gives up to 12 input
captures/output compares/PWMs on the largest packages.
The general-purpose timers can work together with the advanced-control timer via the Timer
Link feature for synchronization or event chaining. Their counter can be frozen in debug
mode. Any of the general-purpose timers can be used to generate PWM outputs. They all
have independent DMA request generation.
These timers are capable of handling quadrature (incremental) encoder signals and the
digital outputs from 1 to 3 hall-effect sensors.
Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 40 kHz internal RC and as it operates independently of the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes. The counter
can be frozen in debug mode.
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from the
main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.
