: Device for byte swap.
Explanations:
1. For 16-bit instruction, high byte and low byte of the register will be swapped.
2. For 32-bit instruction, byte swap is conducted on the 2 registers separately.
3. When SWAP is used as 16-bit instruction, Z device cannot be adopted; when SWAP is used as 32-bit
instruction, V device cannot be adopted.
4. When specifying the bit device of KnX(Y/M/S), the starting No. should be a multiple of 16 in octal or decimal
format. For example, K1X0, K4Y20 (octal); K1M0, K4S16 (decimal).
5. This instruction adopts pulse execution instructions (SWAPP, DSWAPP)
Program Example 1:
When X0 = ON, high byte and low byte of D0 will be swapped.

High Byte Low Byte
Program Example 2:
When X0 = ON, high byte and low byte of D11 will be swapped as well as the high byte and low byte of D10.
