Operands:
S: Device for swapping 8 high/low byte.
Explanations:
1. If D is used in device F, only 16-bit instruction is applicable.
2. See the specifications of each model for their range of use.
3. As 16-bit instruction: the contents in the 8 high bytes and 8 low bytes are swapped.
4. As 32-bit instruction: the 8 high bytes and 8 low bytes in the two registers swap with each other respectively.
5. This instruction adopts pulse execution instructions (SWAPP, DSWAPP).
Program Example 1:
When X0 = On, the high 8 bytes and low 8 bytes in D0 will swap with each other.
