Explanation:
1. When the 16-bit instruction is executed, the data in the low byte in S is exchanged with the
data in the high byte in S.
2. When the 32-bit instruction is executed, the data in the low byte of the high word in S is
exchanged with the data in the high byte of the high word in S, and the data in the low byte of
the low word in S is exchanged with the data in the high byte of the low word in S.
3. Only the 32-bit instructions can use the 32-bit counter.
Example 1:
When X0.0 is ON, the data in the low byte in D0 is exchanged with the data in the high byte in D0.
Example 2:
When X0.0 is ON, the data in the low byte in D11 is exchanged with the data in the high byte in D11,
and the data in the low byte in D10 is exchanged with the data in the high byte in D10.
