Special Math Instructions Section 5-23
Description DBS(––) divides the 32-bit (8-digit) signed binary data in Dd+1 and Dd by the
32-bit signed binary data in Dr+1 and Dr, and outputs the 16-digit signed
binary result to R+3 through R. The quotient is placed in R+1 and R, and the
remainder is placed in R+3 and R+2.
Note Refer to 1-7 Calculating with Signed Binary Data for more details.
Flags ER: Dr+1 and Dr contain 0.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ: ON when the content of R+1 and R (the quotient) is 0, otherwise OFF.
Example In the following example, DBSL(––) is used to divide the signed binary con-
tents of IR 101 and IR 100 with the signed binary contents of DM 0021 and
DM 0020 and output the result to LR 24 through LR 01.
