Description
WAND_W
WAND_DW
ANDB IN1,
OUT
ANDW IN1,
OUT
ANDD IN1,
OUT
The AND Byte, AND Word, and AND Double Word instructions logically AND the corre-
sponding bits of two input values IN1 and IN2 and load the result in a memory location
assigned to OUT.
• LAD and FBD: IN1 AND IN2 = OUT
• STL: IN1 AND OUT = OUT
WOR_W
WOR_DW
ORB IN1,
OUT
ORW IN1,
OUT
ORD IN1,
OUT
The OR Byte, OR Word, and OR Double Word instructions logically OR the correspond-
ing bits of two input values IN1 and IN2 and load the result in a memory location as-
signed to OUT.
• LAD and FBD: IN1 OR IN2 = OUT
• STL: IN1 OR OUT = OUT
WXOR_W
WXOR_DW
XORB IN1,
OUT
XORW IN1,
OUT
XORD IN1,
OUT
The Exclusive OR Byte, Exclusive OR Word, and Exclusive OR Double Word instruc-
tions logically XOR the corresponding bits of two input values IN1 and IN2 and load the
result in a memory location OUT.
• LAD and FBD: IN1 XOR IN2 = OUT
• STL: IN1 XOR OUT = OUT
Non-fatal errors with ENO = 0
SM bits affected
• 0006H Indirect address • SM1.0 Result of operation = zero
