DIV, DIVP: 7 steps

Operands:

S

1

: Dividend S

2

: Divisor D: Quotient and remainder

Explanations:

1.

In 16-bit instruction, D occupies 2 consecutive devices.

2.

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.

16-bit instruction:

+1

=

/

Quotient

Remainder

Program Example:

When X0 = On, D0 will be divided by D10 and the quotient will be stored in D20 and remainder in

D21. On/Off of the highest bit indicates the positive/negative status of the result value.
