Description /BL(435) divides BCD 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, R+3.
Flags
Precautions If Dd, Dd+1 and/or Dr, Dr+1 are not BCD or the content of Dr, Dr+1 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, R+1 is 00000000 hex, the
Equals Flag will turn ON.
Examples When CIO 000000 is ON in the following example, D00101 and D00100 will
be divided by D00111 and D00110 as 8-digit BCD values and the quotient will
be output to D00121 and D00120 and the remainder to D00123 and D00122.
