of the operation is specified as byte, word, or long. Only word and long operations can
be used with address registers, and the condition codes are not affected. When
subtracting from address registers, the entire destination address register is used,
despite the operation size.
X — Set to the value of the carry bit.
N — Set if the result is negative; cleared otherwise.
Z — Set if the result is zero; cleared otherwise.
V — Set if an overflow occurs; cleared otherwise.
C — Set if a borrow occurs; cleared otherwise.
