Function
Hint
• This operation (reversing the status of the bits and adding 1) is equivalent to subtracting the content
of S/S+1 and S from 0000/0000 0000.
Example Programming
When CIO 0.00 is ON in the following example, NEG(160) calculates the 2's complement of the content
of D100 and writes the result to D200.
When CIO 0.00 is ON in the following example, NEGL(161) calculates the 2's complement of the
content of D101 and D100 and writes the result to D201 and D200.
z NEG
NEG(160) calculates the 2's complement of S and writes the result to R. The
2's complement calculation basically reverses the status of the bits in S and
adds 1.
Note The result for 8000 hex will be 8000 hex.
z NEGL
NEGL(161) calculates the 2's complement of S+1 and S and writes the
result to R+1 and R. The 2's complement calculation basically reverses the
status of the bits in S+1 and S and adds 1.
Note The result for 8000 0000 hex will be 8000 0000 hex.
