Operands:

: Device to be exchanged 1 D

: Device to be exchanged 2

Explanations:

1. The contents in the devices designated by D

and D

will exchange

2. It is better to apply a pulse execution for this instruction (XCHP).

3. If operand D1 and D2 use index register F, only 16-bit instruction is available.

Program example:

When X0=OFF→ON, the contents of D20 and D40 exchange with each other.

Points to note:

1. As a 16-bit instruction, when the devices designated by D

and D

are the same and M1303

= ON, the upper and lower 8 bits of the designated devices exchange with each other.

2. As a 32-bit instruction, when the devices designated by D

and D

are the same and M1303

= ON, the upper and lower 16 bits in the designated device exchange with each other.

3. When X0 = ON and M1303 = ON, 16-bit contents in D100 and those in D101 will exchange

with each other.
