Analog Synchronization
PSC generates a signal to synchronize the sample and hold; synchronisation is manda-
tory for measurements.
This signal can be selected between all falling or rising edge of PSCn0 or PSCn1
outputs.
In center aligned mode, all the input values (OT1,OT2,DT1,DT2) are not used. One of
the remainding values can be used to specified the synchronization of the ADC.
Interrupt Handling
As each PSC can be dedicated for one function, each PSC has its own interrupt system
(vector ...)
List of interrupt sources:
• Counter reload (end of On Time 1)
• PSC Input event (active edge or at the beginning of level configured event)
• PSC Mutual Synchronization Error
