y Note:

1. If S, and D are used in device F, only 16-bit instruction is applicable.

16-bit instruction (5 Steps)

MOV

Continuous

execution

32-bit instruction (9 Steps)

DMOV

Continuous

execution

y Flags: None

Operands:

: Source of data

: Destination of data

Explanations:

1. When this instruction is executed, the content of S will be moved directly to D. When this

instruction is not executed, the content of D remains unchanged.

2. If the operation result refers to a 32-bit output, (i.e. application instruction MUL and so on), and

the user needs to move the present value in the 32-bit high-speed counter, DMOV instruction has

to be adopted.

Program Example:

1. MOV instruction has to be adopted in the moving of 16-bit data.

a) When X0 = Off, the content in D10 will remain unchanged. If X0 = On, the value K10 will be

moved to D10 data register.

b) When X1 = Off, the content in D10 will remain unchanged. If X1 = On, the present value T0

will be moved to D10 data register.

2. DMOV instruction has to be adopted in the moving of 32-bit data.

When X2 = Off, the content in (D31, D30) and (D41, D40) will remain unchanged. If X2 = On, the

present value of (D21, D20) will be sent to (D31, D30) data register. Meanwhile, the present

value of C235 will be moved to (D41, D40) data register.
