4.3Macro Operation

„ Definition

 

WORD

16 Bit data (It is made up of continuous 2 bytes, i.e. 16 bits, b15~b0. It can be used to

 

represent 0000~FFFF of hexadecimal system.

DWORD, DW

32 Bit data (It is made up of continuous 2 words, i.e. 32 bits, b31~b0. It can be used to

 

represent 00000000~FFFFFFFF of hexadecimal.)

BYTE

8 Bit data (It is made up of continuous 2 nibbles, i.e. 8 bits, b7~b0. It can be used to

 

represent 00~FF of hexadecimal system.)

Signed

A signed value is a numeric value with polarity. It means that the value is interpreted as

 

essentially the 'plus' sign that can be found in front of a positive number and the

 

'minus' sign that can be found in front of a negative number.

If DW shows after the macro command, it indicates that the command is 32 Bit data, if DW doesn’t display, it indicates that the command is 16 Bit data. When the user set the format of the device as Double Word, there will be two registers used actually. It means that if the user set the format of $0 as Double Word, $0 and $1 will be used for storing data.

If Signed shows after the macro command, it indicates that the command is a numeric value with polarity. If Signed doesn’t display, it indicates that it is a numeric value without polarity.

$10 = $13 + $15

16

Bit data operation, no polarity

 

 

 

 

$0

= $2 + $4 (DW)

32

Bit data operation, no polarity

 

 

 

 

$4

= FADD($4, 1.9) (Signed DW)

32

Bit data operation, with polarity

 

 

 

 

„Arithmetic Operation

Arithmetic Operation divides into three parts: Integer Operation, Floating Point Operation and Trigonometric Function Operation.

Each operand can be internal memory or constant. But it shall be internal memory only when outputting. Please refer to following table 4.3.1 and examples below for more information.

Integer Operation

Command

+

-

*

/

%

Equation

Description

V1=V2 + V2

Addition

V1=V2 - V3

Subtraction

V1 = V2 * V3

Multiplication

V1 = V2 / V3

Division

V1 = V2 % V3

Get Remainder

 

 

Remark

The calculation result can be stored as signed or unsigned WORD and

DWORD.

When the data exceeds the length of designated unit, the data out of range will be discarded.

V1 can be internal memory only.

V2 and V3 can be internal memory or constant.
