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 0.01 is ON in the following example, D201 and D200 will be
divided by D211 and D210 as 8-digit BCD values, the quotient will be output
to D221 and D220, and the remainder will be output to D223 and D222.
