2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (WOR and WORP)
The logical sum (OR) operation is executed to the contents of
and
in units of bit, and the result is
transferred to
.
• While the command input is OFF, the data of the transfer destination
does not change.
• While the command input is ON, the data of the transfer sources
and
do not change.
• When a constant (K) is specified in the transfer sources
and
, it is automatically converted into
the 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).
