Operation
2. 32-bit operation (DAND and DANDP)
The logical product (AND) 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 the binary format.
• The logical product operation is executed in units of bit as shown in the table below (1 ∧ 1 = 1, 0 ∧ 1 = 0, 1 ∧ 0 = 0,
0 ∧ 0 = 0).
