Before the readout, this instruction will firstcheck the input -pointer clear "CLR". If "CLR" is 1, then the Prvalue will be cleared to 0 first before the readout action is carriedout. After the readout is completed, If the Pr value has alreadyreached 16L-1 (the final bit), then the read-to-end flag "END" willbe set to 1. If Pr is less than 16L-1, then the status of pointerincrement "INC" will be checked. If "INC" is 1, then Pr will beincreased by 1. Besides this, pointer clear "CLR" can executeindependently, and is not affected by other input.LMsMsprPrOTB• The effective range of the pointer is 0 to 16L-1.
