When the execution condition is OFF, DIV(33) is not executed and the program
moves to the next instruction. When the execution condition is ON, Dd is divided
by Dr and the result is placed in R and R + 1: the quotient in R and the remainder
in R + 1.
ER: Dd or Dr is not in BCD.
Indirectly addressed DM word is non-existent. (Content of *DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the result is 0.
When IR 00000 is ON with the following program, the content of IR 216 is divided
by the content of HR 09 and the result is placed in DM 0017 and DM 0018. Exam-
ple data and calculations are shown below the program.
