Function
/U
/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.
÷
/UL
/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.
÷
R + 3

When CIO 0.00 is ON in the following example, D100 will be
divided by D110 as 4-digit unsigned binary values and the
D100
quotient will be output to D120 and the remainder will be
output to D121.

When CIO 0.00 is ON in the following example, D100 and
D101 will be divided by D111 and D110 as 8-digit unsigned
D100
hexadecimal values and the quotient will be output to D121
and D120 and the remainder to D123 and D122.
