Binary Calculation Instructions Section 5-21
5-21-9 SIGNED BINARY DIVIDE – DBS(––)
Limitations This instruction is available in the CQM1-CPU4@-E/-EV1 only.
DM 6143 to DM 6655 cannot be used for R.
Description DBS(––) divides the signed binary content of Dd by the signed binary content
of Dr, and outputs the 8-digit signed binary result to R+1 and R. The quotient
is placed in R, and the remainder is placed in R+1.
Note Refer to 1-10 Calculating with Signed Binary Data for more details.
Flags ER: Dr contains 0.
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 content of R (the quotient) is 0000, otherwise OFF.
Example In the following example, DBS(––) is used to divide the signed binary contents
of DM 0010 with the signed binary contents of DM 0020 and output the result
to LR 21 and LR 02.
