Over-Sampling Ratio
The over-sampling ratio (OSR) defines the number of integration cycles per elementary conversion. Its value is
set with the word SET_OSR[2:0] in power of 2 steps (see Table 11) given by:

Elementary Conversions
As mentioned previously, the whole conversion sequence is made of a set of NELCONV elementary incremental
conversions. This number is set with the word SET_NELC[1:0] in power of 2 steps (see Table 12) given by:
