Skip if data memory is 0
Description
If the contents of the specified data memory are 0, the following instruction,
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).
Operation
Skip if [m]=0
