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