F110
1) DIV (Signed Binary Divide)
(1) Saves the result of word data S1 divided by S2, the quotient in D (16-bit), the remainder in D+1.
(2) At this moment, it performs Signed Operation.
2) DDIV (Signed Binary Double Divide)
(1) Saves the result of word data (S1+1,S1) divided by (S2+1,S2), the quotient in (D+1,D), the remainder in
(D+3,D+2).
(2) If operation result is over 2,147,483,648 (h7FFFFFFF) or below -2,147,483,647(hFFFFFFFF), Carry Flag
