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).
