Number
Error
If the value of S1 and S2 is not of BCD format, if the value of S2 is 0
F110
Zero
To be set if operation result is Zero
F111
1) DIVB (BCD Divide)
(1) Saves the result of BCD data S1 divided by S2, the quotient in D, the remainder in D+1.
(2) Based on operation result, Error(F110) or Zero(F111) Flag will be set.

2) DDIVB (BCD Double Divide) Quotient in D, the Remainder
(1) Saves the result of BCD data (S1, S1+1) divided by (S2, S2+1), the quotient in (D, D+1), the remainder in
(D+2, D+3).
(2) Based on operation result, Error(F110) or Zero(F111) Flag will be set.
