11.3.7 From timer (TIMx) to comparators (COMPx)
Timers (TIMx) can be used as blanking window to COMPx (x = 1...7)
The blanking function is described in Section 24.3.6: COMP output blanking.
The blanking sources are given in comparators control and status register (COMP_CxCSR)
bits BLANKSEL[2:0].
Triggering signals
Timer output signal TIMx_Ocx are the inputs to blanking source of COMPx.
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
11.3.8 From internal analog source to ADC (ADCx), comparator (COMPx)
and OPAMP (OPAMPx)
Table 69 provides the ADC channels mapping on GPIOs or internal connections to
temperature sensor (VTS), internal reference voltage VREFINT, VBAT/3 or opampxint_vout.
