USER’S MANUAL 12-1
12: BOOLEAN COMPUTATION INSTRUCTIONS
Introduction
Boolean computations use the AND, OR, and exclusive OR statements as carried out by the ANDW, ORW, and XORW
instructions, respectively. Since the Boolean computation is executed in each scan while the input is on, a level input or
pulse input should be used as required.
41 ANDW (AND Word)
42 ORW (OR Word)
43 XORW (Exclusive OR Word)
Key Operation
Press the ADV key, followed by the advanced instruction number.
ANDW S1(R)
*****

D1(R)
****
S1 · S2 → D1
When input is on, 16-bit word data designated by source operands
S1 and S2 are ANDed, bit by bit. The result is set to destination
operand D1.
S2(R)

S1 = 1 1 1001
S2 = 1 0 1100

When input is on, 16-bit word data designated by source operands
S1 and S2 are ORed, bit by bit. The result is set to destination
operand D1.

D1(R)
****
S1 ⊕ S2 → D1
When input is on, 16-bit word data designated by source operands
S1 and S2 are exclusive ORed, bit by bit. The result is set to desti-
nation operand D1.

Enter operands S1, S2, and D1.
When repeat is required, press the REP key for the operand
to repeat, and enter the number of repeat cycles.
To exit, press the key.
