DIS, DISP

  • When enabled, the DIS instruction moves each 4 bits of source to the lowest bit of number (n) of the Destination.

  • You can choose 1~4 for (n). The bits from b4 to b15 become 0.

  • If n is 0, there will be no change in the Destination.

 

 

 

Example)

If X01 is ON, DISP instruction moves 4bits of D0 to the lowest bit of D20, D21, D22, and D23 (n=4). The lowest 4bits of D0 is stored from starting device D20.

 

 

 

 

UNI, UNIP

  • When enabled, the UNI instruction moves the lowest 4bits from (n) number of source to the Destination.

  • You can choose 1~4 for (n). The bits from b4 to b15 become 0.

  • If n is 0, there will be no change in the Destination.

 

 

Example)

If X03 is ON, UNIPS instruction moves each 4 bits of D20, D21, and D22 (n=3) to D10. The starting device D20 is stored from the lowest bit of D10.
