Operation:
The bit pattern of the selected device is inverted.
This means any occurrence of a ‘1’ becomes a ‘0’
and any occurrence of a ‘0’ will be written as a ‘1’.
When this is complete, a further binary 1 is added to the bit pattern. The result is the total
logical sign change of the selected devices contents, e.g. a positive number will become a
negative number or a negative number will become a positive.
