Logical Instructions (Accumulator)
AND
A aaa
The And instruction is a 16 bit instruction
that logically ands the value in the lower
16 bits of the accumulator with a
specified V--memory location (Aaaa).
The result resides in the accumulator.
The discrete status flag indicates if the
result of the And is zero.
Operand Data Type DL130 Range
A aaa
V--memory V All (See page 4--29)
Discrete Bit Flags Description
SP63 Will be on if the result in the accumulator is zero
NOTE: The status flags are only valid until another instruction that uses the same
flags is executed.
In the following example, when X1 is on, the value in V2000 will be loaded into the
accumulator using the Load instruction. The value in the accumulator is anded
with the value in V2006 using the And instruction. The value in the lower 16 bits of the
accumulator is output to V2010 using the Out instruction.
