When the instruction is executed while M8160 is ON, high-order 8 bits (byte) and low-order 8 bits (byte) of a word
device are exchanged with each other.
Because this instruction works in the same way as SWAP (FNC147) instruction, use SWAP instruction when
programming a new exchange.
In a 32-bit operation, high-order 8 bits (byte) and low-order 8 bits (byte) of each word device are exchanged for each
other.
Error
An operation error occurs in the following case. The error flag M8067 turns ON, and the error code is stored in D8067.
