Timers and watchdogs
The STM32WB55xx and STM32WB35xx include one advanced 16-bit timer, one general-
purpose 32-bit timer, two 16-bit basic timers, two low-power timers, two watchdog timers
and a SysTick timer. Table 13 compares the features of the advanced control, general
purpose and basic timers.

Advanced-control timer (TIM1)
The advanced-control timer can be seen as a three-phase PWM multiplexed on six
channels. They have complementary PWM outputs with programmable inserted
dead-times. They can also be seen as complete general-purpose timers. The four
independent channels can be used for:
Input capture
Output compare
PWM generation (edge or center-aligned modes) with full modulation capability (0 to
100%)
One-pulse mode output
In debug mode, the advanced-control timer counter can be frozen and the PWM outputs
disabled to turn off any power switches driven by these outputs.
Many features are shared with those of the general-purpose TIMx timers (described in
Section 3.20.2) using the same architecture, so the advanced-control timers can work
together with the TIMx timers via the Timer Link feature for synchronization or event
chaining.
General-purpose timers (TIM2, TIM16, TIM17)
There are up to three synchronizable general-purpose timers embedded in the
STM32WB55xx and STM32WB35xx (see Table 13 for differences). Each general-purpose
timer can be used to generate PWM outputs, or act as a simple time base.
