/UL(433) divides the unsigned binary values in Dd and Dd+1 by those in Dr
and Dr+1 and outputs the quotient to R, R+1 and the remainder to R+2, and
R+3.

Negative Flag N
When the content of Dr, Dr+1 is 0, the Error Flag will turn ON.
If as a result of the division, the content of R, R+1, is 0000 hex, the Equals
Flag will turn ON.
If as a result of the division, the content of the leftmost bit of R+1 is 1, the Neg-
ative Flag will turn ON.
When CIO 000000 is ON in the following example, D00100 and D00101 will
be divided by D00111 and D00110 as 8-digit unsigned hexadecimal values
