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:
S
: Source of data
D
: 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.
