Explanation of function and operation
1. 16-bit operation (WAND and WANDP)
The logical product (AND) 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 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).
1: ON, 0: OFF
