y Note:

1. If S

and S

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.

16-bit instruction (7 Steps)

DIV

Continuous

32-bit instruction (13 Steps)

DDIV

Continuous

y Flags: None

Operands:

: Dividend

: Divisor

: Quotient and remainder

Explanations:

1. This instruction divides S

and S

in BIN format and stores the result in D. Be careful with the

positive/negative signs of

, S

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,

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 +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.
