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:
Quotient
S1 S2 D D
Remainder
b15.............b00 b15.............b00 b15.............b00 b15.............b00

=
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.
6. 32-bit BIN division:
Quotient
Remainder
S1 +1 S1 S2 +1 S2 D +1 D D +3 D +2
b15..b00 b15..b00 b15..b00 b15..b00 b31..b16 b15..b00 b31..b16 b15..b00
/ =
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..
