RM0444
Triggering signals
The output (from ADC) is on signals ADCn_AWDx_OUT n = 1, 2, 3 (for ADC) x = 1, 2, 3
(three watchdogs per ADC) and the input (to timer) on signal TIMx_ETR (external trigger).
Relevant power modes
This interconnection operates in Run, Sleep, Low-power run, and Low-power sleep power
modes.

From TIM1, TIM2, TIM3, TIM4, TIM6, TIM7, TIM15, LPTIM1, LPTIM2,

and EXTI, to DAC

Purpose
General-purpose timers TIM2/TIM3/TIM4/TIM15, basic timers TIM6, TIM7, low-power
timers LPTIM1/LPTIM2, and advanced control timer TIM1 can trigger a DAC conversion.
Triggering signals
The TIMx_TRGO output of each timer is directly connected to corresponding DAC input.
Selection of DAC triggering input is provided in
and dual mode).
Relevant power modes
These interconnections operate in Run, Sleep, Low-power run, and Low-power sleep power
modes.
9.3.5

From HSE, LSE, LSI, MCO, MCO2, RTC and TAMP, to TIM2, TIM14,

TIM16, and TIM17

Purpose
External clocks (HSE, LSE), internal clock (LSI), microcontroller output clock (MCO and
MCO2), RTC clock, RTC wakeup interrupt, and GPIO can be selected as inputs to capture
channel 1 of some of TIM14/16/TIM17 timers.
The timers allow calibrating or precisely measuring internal clocks such as HSI16 or LSI,
using accurate clocks such as LSE or HSE/32 for timing reference. See details in
Section 5.2.16: Internal/external clock measurement with
When low-speed external (LSE) oscillator is used, no additional hardware connections are
required.
External clock LSE can be used as input to general-purpose timers (TIM2) on TIM2_ETR
input, see
Relevant power modes
These interconnections operate in Run, Sleep, Low-power run, and Low-power sleep power
modes.
