Description: Subtracts the destination operand and the extend bit from zero. The operation
Condition Codes:
MOTOROLA
is performed using binary-coded decimal arithmetic. The packed binary-coded decimal
result is saved in the destination location. This instruction produces the tens
complement of the destination if the extend bit is zero or the nines complement if the
extend bit is one. This is a byte operation only.
X — Set the same as the carry bit.
N — Undefined.
Z — Cleared if the result is nonzero; unchanged otherwise.
V — Undefined.
C — Set if a decimal 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.
