From VREFINT to ADC

VREFINT is internally connected to channel 18 of the ADCs. This allows the monitoring of
its value as described in
7.3.9

From COMP to TIM

The comparators outputs can be redirected internally to different timer inputs:
•
break input 1/2 for fast PWM shutdowns,
•
OCREF_CLR input,
•
Input capture.
To select which timer input must be connected to the comparator output, the bits field
COMPxOUTSEL in the COMPx_CSR register are used.
The following table gives an overview of all possible comparator outputs redirection to the
timer inputs.
