NOT (WORD)
The NOT function is used to set the state of each bit in the output bit string Q to the opposite of the
state of the corresponding bit in bit string I1.
All bits are altered on each scan that power is received, making output string Q the logical
complement of I1. The function passes power flow to the right whenever power is received.
