For sampling, it starts when the set start condition is satisfied after executing the CntSamplingStart function, and stops in cases when the set stop condition is satisfied, specified buffer area is filled with transferred data, or compulsive stop is executed by the CntSamplingStop function.
In the case of software start, sampling starts after the CntSamplingStart function is executed.
The software stop (the function of CntSamplingStop) is valid whatever the stop condition is.
