Exclusive Or Double (XORD)
The Exclusive Or Double is a 32-bit instruction that
performs an exclusive OR of the value in the
accumulator and the value (Kaaa), which is an
8-digit (max.) constant. The result resides in the
accumulator. Discrete status flags indicate if the
result of the Exclusive Or Double is zero or a
negative number (the most significant bit is on).
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 and V2001 will be loaded into
the accumulator using the Load Double instruction. The value in the accumulator is
exclusively ORed with 36476A38 using the Exclusive Or Double instruction. The value in
the accumulator is output to V2010 and V2011 using the Out Double instruction.
