DOUBLE BCD DIVIDE
When the execution condition is OFF, /BL(435) is not executed. When the
execution condition is ON, the BCD 8-digit content of Dd and D+1 is divided by
the BCD content of Dr and Dr+1 and the result is placed in R to R+3: the quotient
in R and R+1, and the remainder in R+2 and R+3.
R+3
Dr+1
Dd and Dr (or Dd, Dd+1, Dr, and Dr+1) must be BCD. If any other data is used,
the Error Flag (A50003) will turn ON and the instruction will not be executed.
Note Refer to page 101 for general precautions on operand data areas.
ER (A50003): Dd and Dr (or Dd, Dd+1, Dr, and Dr+1) are not BCD.
The content of a*DM word is not BCD when set for BCD.
EQ(A50006) The division result is all zeroes.
/BL Operation
When CIO 000001 is ON in the following example, the content of D00201 and
D00200 is divided by the content of D00211 and D00210, in eight-digit BCD.
When the result is obtained, the quotient is output to D00221 and D00220, and
the remainder is output to D00223 and D00222.
