With a resolution of 12bit plus sign bit, the least significant bits (3bit) are not relevant.
The algebraic sign bit is represented by Bit 15. Here it is essential:
n
Bit 15 = "0":
à
positive value
n
Bit 15 = "1":
à
negative value
4.3 Output ranges and function numbers
In the following there are the output ranges listed with function number, which were sup-
ported by the corresponding analog module. The here listed formulas allow you to trans-
form a value (digital value) to an analog value and vice versa.
