ADC_SM_1
Multiple acquisition by application software
End user
This method implements a timing information redundancy by executing multiple acquisitions on the
same input signal. Multiple acquisition data are then combined by a filter algorithm to determine the
signal correct value

CPU_SM_0: periodical core self-test software
It is highly probable that this recommendation is satisfied by design by the end user application
software. Usage of multiple acquisitions followed by average operations is a common technique in
industrial applications where it is needed to survive with spurious EMI disturbs on sensor lines
