
The singed binary value in S
1
is divided by the signed binary value in S
2
.
The quotient and the remainder are stored in D . Users have to notice the
sign bits in S
1
, S
2
, and D when 16-bit binary division or 32-bit binary
division is done.

S
1
: Dividend; S
2
: Divisor; D : Quotient and remainder

If the divisor in S
2
is 0, the instruciton will not be executed.

When X0.0 is ON, the dividend in D0 is divided by the divisor in D10, the
quotient is stored in D20, and the remainder is stored in D21. Whether
the quotient and the remainder are positive values or negative values
depends on the leftmost bit in D20 and the leftmost bit in D21.
