5.3.16 One’s Complement (COM)
( 1 ) Operation
The one’s complement of the input data is stored in the output data.
Œ This instruction inverts the 0’s and 1’s in the binary representation of the input data and stores the result in the
output data.
( 2 ) Format
∗ C and # registers cannot be used.
( 3 ) Programming Example
In the following programming example, the one’s complement of -3,856 (F0F0 hex) in the input data in MW00000 is
stored in the output data in MW00001.
MW00000 = -3,856 (F0F0 hex)
→ MW00001 = 3,855 (0F0F hex)
When performing operations with different data types, the result of the operation will depend on the data type of the output reg-
ister.
