Processing details
• These instructions invert the sign of the 32-bit binary data in the device specified by (d), and store the resultant data in the
device specified by (d).
• They are used when a positive or negative sign is to be inverted.
Precautions
Note that data is inverted in every operation cycle in a continuous operation type (DNEG) instruction.
Operation error
There is no operation error.
