Explanation of function and operation
1. 16-bit operation (WAND and WANDP)
The logical product (AND) operation is executed to the contents of
transferred to D
Command
input
FNC 26
WAND
• While the command input is OFF, the data of the transfer destination
• While the command input is ON, the data of the transfer sources
• When a constant (K) is specified in the transfer sources
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).
