Operation
2. 32-bit operation (DOR and DORP)
The logical sum (OR) operation is executed to the contents of [ +1, ] and [ +1, ] in units of bit,
and the result is transferred to [ +1, ].
• While the command input is OFF, the data of the transfer destination [ +1, ] does not change.
• While the command input is ON, the data of the transfer source [ +1, ] [ +1, ] do not
change.
• When a constant (K) is specified in the transfer source [ +1, ] [ +1, ], it is automatically
converted into binary format.
• The logical sum operation is executed in units of bit as shown in the table below (1 ∨ 1 = 1, 0 ∨ 1 = 1,
0 ∨ 0 = 0, 1 ∨ 0 = 1).
