SNZ [m].i
Skip if bit i of the data memory is not 0.
Description
If bit i of the specified data memory is not 0, the next instruction is skipped.
If bit i of the data memory is not 0, the following instruction, fetched during
the current instruction execution, is discarded and a dummy cycle is re-
placed to get the proper instruction (2 cycles). Otherwise proceed with the
next instruction (1 cycle).
Operation
Skip if [m].i 0
