Description
/B(434) divides the BCD content of Dd by those of Dr and outputs the quotient
to R and the remainder to R+1.
Flags
Precautions
If Dd or Dr are not BCD or if the remainder (R+1) is 0, an error will be gener-
ated 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 leftmost bit of R is 1, the Negative Flag will
turn ON.
Examples
When CIO 000000 is ON in the following example, D00100 will be divided by
D00110 as 4-digit BCD values and the quotient will be output to D00120 and
the remainder to D00120.
Example in Function Block Definition
In the following example, an array variable is used to get the quotient and
remainder from the function block.
