NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V2000 and V2001 will be loaded
into the accumulator using the LDD instruction. The value in the accumulator is exclusively
ORed with 36476A38 using the XORD instruction. The value in the accumulator is output to
V2010 and V2011 using the OUTD instruction.

Exclusive Or Double (XORD)
The XORD is a 32-bit instruction that performs an exclusive
OR of the value in the accumulator and the value (Aaaa),
which is either two consecutive V-memory locations or an 8
digit (max.) constant. The result resides in the accumulator.
Discrete status flags indicate if the result of the XORD is zero
or a negative number (the most significant bit is on).
