Beforeexecuting, this instruction will first check the input signal of pointer clear "CLR". If "CLR" is 1, it will first clear Prand then carry out the move operation. After completing the move operation, it will then check the value of Pr.If the Pr value has already reached L-1 (point to the last register in the table), then it sets the move-to-end flagto 1, and finishes executing of this instruction. If Pr is less than L-1, it check the status of "INC". If "INC" is 1,then it will increase Pr and finish the execution of this instruction. Besides, pointer clear "CLR" can executeindependently and is not influenced by other inputs.• The effective range of the pointer is 0 to L-1. Beyond this range the pointer error "ERR" will be set to 1 and thisinstruction will not be carried out.X0101P.T REN TS : R 0L : 9INC Pr : R 19Rd : R 20CLRENDERR• In the example at left, at the very beginning Pr = 7 and Tsand Rd are as shown at left in the diagram below.
