1) DIVU (Unsigned 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) Performs Unsigned Operation.
2) DDIVU (Unsigned 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) Performs Unsigned Operation.
3) Program Example
(1) For P1000=’5559’ and P1100=’5’, Input Signal is changed from Off to On status, the quotient of Unsigned
division ‘1111’ is saved in P1200 and the remainder ‘4’ is saved in P1201.
