 Note: The instruction supports V devices and Z devices. (If the 16-bit
instruction is used, Z devices can not be used. If the 32-bit
instruction is used, V devices can not be used.)

Explanation
 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.

Example

When X0 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.
