Table 4-2-2: Unsigned Integer representation as follows:
The output value is represented with 15-bit resolution without sign, therefore polarity detection is
no longer possible. Maximum representation range for 16 bits = 0 to +32767dec

Table 4-2-3: Absolute value with MSB as sign - representation
as follows:
The output value is displayed in magnitude-sign format: MSB=1 (highest bit) in the case of negative
values. Maximum representation range for 16 bits = -32767 to +32767dec
