10.3.9 From timer (TIM1/TIM2/TIM3/TIM8/TIM15) to comparators
(COMP1/COMP2)
Purpose
Advanced-control timers (TIM1/TIM8), general-purpose timers (TIM2/TIM3) and general-
purpose timer (TIM15) can be used as blanking window input to COMP1/COMP2
The blanking function is described in Section 22.3.7: Comparator output blanking function.
The blanking sources are given in:
• Section 22.6.1: Comparator 1 control and status register (COMP1_CSR) bits 20:18
BLANKING[2:0]
• Section 22.6.2: Comparator 2 control and status register (COMP2_CSR) bits 20:18
BLANKING[2:0]
Triggering signals
Timer output signal TIMx_Ocx are the inputs to blanking source of COMP1/COMP2.
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.10 From ADC (ADC1) to ADC (ADC2)
Purpose
ADC1 can be used as a “master” to trigger ADC2 “slave” start of conversion.
In dual ADC mode, the converted data of the master and slave ADCs can be read in
parallel.
A description of dual ADC mode is provided in: Section 18.4.31: Dual ADC modes.
Triggering signals
Internal to the ADCs.
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.11 From USB to timer (TIM2)
Purpose
USB (OTG_FS SOF) can generate a trigger to general-purpose timer (TIM2).
Connection of USB to TIM2 is described in Table 192: TIMx internal trigger connection.
Triggering signals
Internal signal generated by USB FS Start Of Frame.
Active power mode
Run, Sleep.
