11.2 Logic gate
A logic gate has up to 4 Boolean inputs (1 bit) and one logic output (1 bit). In con-
sequence, a logic operation only supports the 1-bit data format. The following table
shows configurable comparison operations Logic gate and explains their function.

Description
The logic gate has only one input. The input is for-
warded to the gate output inverted.
Logic gate has 4 inputs. The output is "1" if all in-
puts are "1". Otherwise the output is "0".
Logic gate has 4 inputs. The output is "0" if all in-
puts are "0". Otherwise the output is "1".
Logic gate has 4 inputs. The output is "1" if only

Logic gate has 4 inputs. The output is "1" if all in-
puts are "0". Otherwise the output is "0".
Logic gate has 4 inputs. The output is "0" if only
one input is "1". Otherwise the output is "1".
Logic gate has 4 inputs. The output is fed back to
the first input of the gate.
The output is "1" if all inputs are "1". Otherwise the
output is "0".
If input 1 is set to "1" and the output is still "0", the
feedback of input 1 is also reset to "0". Only when
