6 Application Instructions API 00-49 API 28 Operands: S 1 : Source data device 1 S 2 : Source data device 2 D : Operation result Explanations: 1. If S 1 , S 2 and D are used in device F, only 16-bit instruction is applicable. 2. See the specifications of each model for their range of use. 3. This instruction conducts logical XOR operation of S 1 and S 2 and stores the result in D . 4. Operation rule: If the bits in S 1 and S 2 are the same, the corresponding bit of the operation result in D will be “0”; if the bits in S 1 and S 2 are different, the corresponding bit of the operation result in D will be “1”. Program Example 1:
When X0 = On, the 16-bit D0 and D2 will perform WXOR, logical XOR operation, and the result will be stored in D4. X0 b15 0 0 0 0 0 0 1 1 b0 Before execution D0 0 0 1 1 1 1 1 1 D2 0 0 0 0 0 0 1 1 1 1 0 1 1 1 0 1 WOR After execution D4 Program Example 2: When X1 = On, the 32-bit (D11, D10) and (D21, D20) will perform DXOR, logical XOR operation, and the result will be stored in (D41, D40).
