Condition Bits Affected:
Example:
UM008005-0205
S is set if most-significant bit of Accumulator is 1 after operation; reset
otherwise
Z is set if Accumulator is zero after operation; reset otherwise
H, see instruction
P/V is set if Accumulator is even parity after operation; reset otherwise
N is not affected
C, see instruction
If an addition operation is performed between 15 (BCD) and 27 (BCD),
simple decimal arithmetic gives this result:
But when the binary representations are added in the Accumulator
according to standard binary arithmetic.
the sum is ambiguous. The
correct BCD representation is obtained:
