) – FNC 20 to FNC 29

10.4 FNC 23 – DIV / Division

2. 32-bit operation (DDIV and DDIVP)

[

+1,

] indicates the dividend, [

+1,

] indicates the divisor, the quotient is transferred to

[

+1,

]), and the remainder is transferred to [

+3,

+2].

• Four devices in total starting from

are occupied to store the operation result (quotient and remainder). Make

sure that these four devices are not used for another control.

• The most significant bit of each data indicates the sign (positive: 0 or negative: 1), and data is divided algebraically.

• When a constant (K) is specified in [

+1,

] or [

+1,

], it is automatically converted into binary

format.

Cautions

1. Operation result

• The most significant bit of the quotient and remainder indicates the sign (positive: 0, negative: 1) respectively.
• The quotient is negative when either the dividend or divisor is negative.

The remainder is negative when the dividend is negative.

2. Device specified as

• The remainder is not obtained when a bit device is specified with digit specification.

• In a 32-bit operation (by DDIV or DDIVP), Z cannot be specified as

.

Error

• When the divisor

is "0", an operation error is caused and the instruction is not executed.

• A operation error results when the operation result is over 32,767 (16-bit operation) or 2,147,483,647 (32-bit

operation). (Turns the carry flag ON.)

Zero

ON : When the operation result is 0.
OFF : When the operation result is a number other than 0.

M8306*1

Carry

ON : Carry flag operates when the operation result is over 32,767 (16-bit operation)

or2,147,483,647 (32-bit operation).

OFF : When the operation result is less than 32,767 (16-bit operation) or 2,147,483,647

(32-bit operation).
