2. 32-bit operation (DSUM and DSUMP)
The number of bits in the ON status in [ +1, ] is counted, and stored to .
• The number of bits in the ON status are stored in , and K0 is stored in +1.
• When all bits are OFF in [ +1, ], the zero flag M8020 turns ON.
3. Operation result according to the value (in 16-bit operation)
