16.7.3
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:
16.7.4
As mentioned previously, the whole conversion sequence is made of a set of N
conversions. This number is set with the word SET_NELC[1:0] in power of 2 steps (see Table 16-21) given by:
