Calculating output values using 1 of n mode

Set Mode to 1 of n to enable this functionality. In this mode, only one of the inputs can go high at any
given time. If more than one input goes high, an error is detected and the ERROR output is set
TRUE. If none of the inputs are high, the input is not detected and the NOINP output is set to TRUE.
The output is set to the default output if ERROR and/or NOINP outputs are TRUE. The output
evaluated as per the setting of input mode is as shown in
