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 will be loaded into the accumulator
using the LD instruction. The value in the accumulator is exclusive ORed with V2006 using
the XOR instruction. The value in the lower 16 bits of the accumulator is output to V2010
using the OUT instruction.

Exclusive Or (XOR)
The XOR instruction is a 16-bit instruction that performs
an exclusive OR of the value in the lower 16 bits of the
accumulator and a specified V-memory location (Aaaa).
The result resides in the in the accumulator. The discrete
status flag indicates if the result of the XOR is zero.
