Exclusive Or (XOR)
The Exclusive Or instruction is a 16-bit instruction that
230
performs an exclusive OR of the value in the lower 16 bits of the
240
accumulator and a specified V-memory location (Aaaa). The
250-1
result resides in the accumulator. The discrete status flag
260 indicates if the result of the XOR 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 exclusive ORed with
V2006 using the Exclusive Or instruction. The value in the lower 16 bits of the accumulator
are output to V2010 using the Out instruction.
