5.4.1.10 DIGITAL COMPARATOR (PSR-M-B2)
The digital comparator enables the comparison (in binary form) of one signal group with a
constant or of two signal groups.
Parameters
Signals comparator (deac-
tivated)/comparison with
constant
Figure 5-100 “DIGITAL COMPARATOR” operator (comparison with constant)
In order to perform a comparison with a constant, the “Signals comparator” parameter must
not be selected.
Inputs number The “DIGITAL COMPARATOR” operator enables the comparison of a series of input sig-
nals (from 2 to a maximum of 8) with a constant decimal value that can vary from “0” to “255”.
Input “I
N 1” is the least significant bit; input “IN 8” (or “In 2” ... “In 7” if the number of inputs is
reduced) is the most significant bit:
