Description /(430) divides the signed binary (16 bit) values in Dd by those in Dr and out-
puts the result to R, R+1. The quotient is placed in R and the remainder in
R+1.
Flags
Precautions When the content of Dr is 0, an error will be generated and 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 signed binary values and the quotient will be output to
D00120 and the remainder to D00121.
