tion, fetched during the current instruction execution, is discarded and a
dummy cycle is replaced to get the proper instruction (2 cycles). Otherwise
proceed with the next instruction (1 cycle).

Description
Thecontentsofthespecifieddatamemoryaredecrementedby1.Iftheresult
is 0, the next instruction is skipped. The result is stored in the accumulator
but the data memory remains unchanged. If the result is 0, the following in-
struction, fetched during the current instruction execution, is discarded and
a dummy cycle is replaced to get the proper instruction (2 cycles). Otherwise
proceed with the next instruction (1 cycle).
