Before the execution, assume D10 = H1234 and D20 = H5678. After the execution, D10 will remain unchanged and
D20 will become H5128.
Program Example 3:
1.
This instruction can be used to combine the DIP switches connected to the input terminals with interrupted No.
2.
Move the 2
nd
right digit of the DIP switch to the 2
nd
right digit of D2, and the 1
st
left digit of the DIP switch to the
1
st
right digit of D1.
3.
Use SMOV instruction to move the 1
st
digit of D1 to the 3
rd
digit of D2 and combine the two DIP switches into
one.
