SZ [m]
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 in-
struction (2 cycles). Otherwise proceed with the next instruction (1 cycle).
