y Note:
1. If S
1
and S
2
are used in device F, only 16-bit instruction is applicable.
2. If D is used in device E, only 16-bit instruction is applicable.

y Flags: None
Operands:
S
1
: Dividend
S
2
: Divisor
D
: Quotient and remainder
Explanations:
1. This instruction divides S
1
and S
2
in BIN format and stores the result in D. Be careful with the
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.
3. In 16-bit BIN division,
+1
=/
Quotient
Remainder
When D serves as a bit device, it can designate K1 ~ K8 and construct a 32-bit result, and
bringing forth the quotient and remainder.
4. In 32-bit BIN division,
+1
/
=
+1 +1 +3 +2
Quotient
Remainder
When D serves as a bit device, it can designate K1 ~ K8 and construct a 32-bit result, and
bringing forth only quotient without the remainder.
