Description /U(432) divides the unsigned binary values in Dd by those in Dr and outputs
the quotient to R and the remainder to R+1.
Flags
Precautions If as a result of the division, the content of R+1 is 0, the Error Flag will turn
ON.
If as a result of the division, the content of R is 0000 hex, the Equals Flag will
turn ON.
If as a result of the division, the content of the leftmost bit of R is 1, the Nega-
tive Flag will turn ON.
Examples When CIO 000000 is ON in the following example, D00100 will be divided by
D00110 as 4-digit unsigned binary values and the quotient will be output to
D00120 and the remainder will be output to D00121.
