Chapter 5 Applied Instructions In order to prevent the error which results from the overlap between source devices and destination devices, the values in the source devices are transferred in the following way. 1. The device number of S is greater than the device number of D . The Example 3 values in D20~D22 are transferred in the order → → . X2.0 D19 D20 D20 2 1 2. The device number of S is less than the device number of D . The values in D10~D12 are transferred in the order → → . The values in D11~D13 are the same as the value in D10. D21 D22 3 D21 X2.1 D10 3 2 D11 D11 D12 1 D12 D13 5-33 BMOV D20 D19 K3 BMOV D10 D11 K3
