SAM9G35
The output of the procedure is the error location polynomial named smu (sigma mu). The poly-
nomial coefficients belong to the field. The smu[NB_ERROR+1][] is a table that contains all
these coefficients.
NB_ERROR_MAX defines the maximum value of the error correcting capability.
NB_ERROR defines the error correcting capability selected at encoding/decoding time.
NB_FIELD_ELEMENTS defines the number of elements in the field.
