Introduction
Boolean computations use the AND, OR, and exclusive OR statements as carried out by the ANDW, ORW, and XORW instructions in
the word or double-word data, respectively.

ANDW (AND Word)

ANDW(*) S1(R)
*****
S1 = 1
S2 = 1
D1 = 1

ORW (OR Word)

ORW(*) S1(R)
*****
S1 = 1
S2 = 1
D1 = 1

XORW (Exclusive OR Word)

XORW(*) S1(R)
*****
S1 = 1
S2 = 1
D1 = 0

S1 · S2 → D1
When input is on, 16- or 32-bit data assigned by source devices S1 and S2
are ANDed, bit by bit. The result is set to destination device D1.
