10.3.1 From timer (TIM1/TIM2/TIM3/TIM4/TIM5/TIM8/TIM15/TIM16/TIM17) to
timer (TIM1/TIM2/TIM3/TIM4/TIM5/TIM8/TIM15)
Purpose
Some of the TIMx timers are linked together internally for timer synchronization or chaining.
When one timer is configured in Master Mode, it can reset, start, stop or clock the counter of
another timer configured in Slave Mode.
A description of the feature is provided in: Section 31.3.19: Timer synchronization.
The modes of synchronization are detailed in:
• Section 30.3.26: Timer synchronization for advanced-control timers (TIM1/TIM8)
• Section 31.3.18: Timers and external trigger synchronization for general-purpose
timers (TIM2/TIM3/TIM4/TIM5)
• Section 32.4.17: External trigger synchronization (TIM15 only) for general-purpose
timer (TIM15)
Triggering signals
The output (from Master) is on signal TIMx_TRGO (and TIMx_TRGO2 for TIM1/TIM8)
following a configurable timer event.
The input (to slave) is on signals TIMx_ITR0/ITR1/ITR2/ITR3
The input and output signals for TIM1/TIM8 are shown in Figure 211: Advanced-control
timer block diagram.
The possible master/slave connections are given in:
• Table 187: TIMx internal trigger connection
• Table 192: TIMx internal trigger connection
• Table 195: TIMx Internal trigger connection
