10.3.4 From timer (TIM2/TIM4/TIM5/TIM6/TIM7/TIM8) and EXTI to DAC
(DAC1/DAC2)
Purpose
General-purpose timers (TIM2/TIM4/TIM5), basic timers (TIM6, TIM7), advanced-control
timers (TIM8) and EXTI can be used as triggering event to start a DAC conversion.
Triggering signals
The output (from timer) is on signal TIMx_TRGO directly connected to corresponding DAC
inputs.
Selection of input triggers on DAC is provided in Section 19.3.6: DAC trigger selection
(single and dual mode).
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.5 From timer (TIM1/TIM3/TIM4/TIM6/TIM7/TIM8/TIM16) and EXTI to
DFSDM1
Purpose
General-purpose timers (TIM3/TIM4), basic timers (TIM6/TIM7), advanced-control timers
(TIM1/TIM8), general-purpose timer (TIM16) and EXTI can be used to generate a triggering
event on DFSDM1 module (on each possible data block
DFSDM1_FLT0/DFSDM1_FLT1/DFSDM1_FLT2/DFSDM1_FLT3) and start an ADC
conversion.
DFSDM triggered conversion feature is described in: Section 24.4.15: Launching
conversions.
Triggering signals
The output (from timer) is on signal TIMx_TRGO/TIMx_TRGO2 or TIM16_OC1.
The input (on DFSDM1) is on signal DFSDM1_INTRG[0:8].
The connection between timers, EXTI and DFSDM1 is provided in Table 154: DFSDM
triggers connection.
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.6 From DFSDM1 to timer (TIM1/TIM8/TIM15/TIM16/TIM17)
Purpose
DFSDM1 can generate a timer break on advanced-control timers (TIM1/TIM8) and general-
purpose timers (TIM15/TIM16/TIM17) when a watchdog is activated (minimum or maximum
threshold value crossed by analog signal) or when a short-circuit detection is made.
DFSDM1 watchdog is described in Section 24.4.10: Analog watchdog.
DFSDM1 short-circuit detection is described in Section 24.4.11: Short-circuit detector.
