Operands:
S
1
: Dividend S
2
: Divisor D: Quotient and remainder
Explanation:
1. This instruction divides S
1
and S
2
in BIN format and stores the result in D. Care should be
taken on positive/negative signs of S
1
, S
2
and D when doing 16-bit and 32-bit operations .
2. This instruction will not be executed when the divisor is 0. M1067 and M1068 will be ON and
D1067 records the error code 0E19 (hex).
3. If operands S
1
, S
2
use index F, then only 16-bit instruction is available.
4. If operand D use index E, then only 16-bit instruction is available.
5. 16-bit BIN division:

If D is specified with a bit device, it can designate K1 ~ K4 to store a 16-bit result. Users can
use consecutive 2 16-bit registers to store 32-bit data of the quotient and remainder.

If D is specified with a bit device, it can designate K1 ~ K8 to store a 32-bit result. Users can
use consecutive 2 32-bit registers to store the quotient and remainder.
Program Example:
When X0 = ON, D0 will be divided by D10 and the quotient will be stored in D20 and remainder in
D21. ON/OFF of the MSB indicates the positive/negative status of the result value..
