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
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
DFSDM1 short-circuit detection is described in
Timer break is described in:
•
Section 37.3.16: Using the break function
•
Section 39.4.13: Using the break function
Triggering signals
The output (from DFSDM1) is on signals dfsdm1_break[0:3] directly connected to timer and
'Ored' with other break input signals of the timer.
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.7 From HSE, LSE, LSI, MSI, MCO, RTC to timer
(TIM2/TIM15/TIM16/TIM17)
Purpose
External clocks (HSE, LSE), internal clocks (LSI, MSI), microcontroller output clock (MCO),
GPIO and RTC wakeup interrupt can be used as input to general-purpose timer
(TIM15/16/17) channel 1.
This allows to calibrate the HSI16/MSI system clocks (with TIM15/TIM16 and LSE) or LSI
(with TIM16 and HSE). This is also used to precisely measure LSI (with TIM16 and HSI16)
or MSI (with TIM17 and HSI16) oscillator frequency.
When Low Speed External (LSE) oscillator is used, no additional hardware connections are
required.
This feature is described in
TIM15/TIM16/TIM17.
