7.6.2.1.6
RS Flip-Flop V1
Overview
The function block saves the most recent value for the
Set
or
Reset
inputs and is used as
a simple memory cell.
Principle of operation
Table 28: Inputs
Input
Description
Set
Data type: Boolean
The
Reset
input has a higher priority than the
Set
input.
Reset

Description
Q
Data type: Boolean
•
If the
Reset
input = 1, then the output = 0.
•
If the
Set
input = 1 and the
Reset
input = 0, then the output = 1.
•
If the
Set
input = 0 and the
Reset
input = 0, then the output keeps
the last value.
/Q
Data type: Boolean
The value at the output is the inverted value of the Q output.

Parameter
Description
Inverted
You can individually invert any visible input. At an inverted input, a 0
works internally in the same way as a 1 and vice versa.
