EXPLANATION
Contents of accumulator are BCD,
IF [[(A3-0 ) > 9] OR
[(AC) = 1]] THEN
(A3-0 ) = (A3-0 ) + 6
AND
IF [[(A7-4 ) > 9] OR
[(C) = 1]] THEN
(A7-4 ) = (A7-4 ) + 6
(A) = (A) AND (Rn)
(A) = (A) AND (direct)
(A) = (A) AND ((Ri))
(A) = (A) AND #data
(direct) =
(direct) AND A
(direct) =
(direct) AND #data
(A) = (A) OR (Rn)
(A) =
(A) OR (direct)
(A) = (A) OR ((Ri))
(A) = (A) OR #data
(direct) =
(direct) OR (A)
(direct) =
(direct) OR #data
(A) = (A) XOR (Rn)
(A) =
(A) XOR (direct)
(A) = (A) XOR ((Ri))
(direct) =
(A) XOR #data
(direct) =
(direct) XOR (A)
(direct) =
(direct) XOR #data
(A) = 0
(A) = (A)
