Exclusive Or (XOR)
The Exclusive Or 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 accumulator. The discrete status flag 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 OR’d 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.
