16.7.3 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 16-20) given by:
OSR = 23 + SET_OSR[2 : 0]

16.7.4 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 16-21) given by:
NELCONV = 2SET_NELC[1: 0]
