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.
