Function
/
/(430) divides the signed binary (16 bit) values in Dd by those in Dr and outputs the result to R, R+1.
The quotient is placed in R and the remainder in R+1.
Note Division of hexadecimal #8000 by #FFFF is undefined.
/L
/L(431) divides the signed binary values in Dd and Dd+1 by those in Dr and Dr+1 and outputs the result
to R, R+1, R+2, and R+3. The quotient is output to R and R+1 and the remainder is output to R+2 and
R+3.
Note Division of hexadecimal #80000000 by #FFFFFFFF is undefined.
