result in the destination location. The size of the operation is specified as byte, word,
or long.
X — Set the same as the carry bit.
N — Set if the result is negative; cleared otherwise.
Z — Cleared if the result is nonzero; unchanged otherwise.
V — Set if an overflow occurs; cleared otherwise.
C — Set if a borrow occurs; cleared otherwise.
X
Normally the Z condition code bit is set via programming before
the start of the operation. This allows successful tests for zero
results upon completion of multiple-precision operations.
