Skip if data memory is 0
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).
Skip if [m]=0
Move data memory to ACC, skip if 0
The contents of the specified data memory are copied to the accumulator. If the contents is
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).
Skip if [m]=0
Skip if bit i of the data memory is 0
If bit i of the specified data memory is 0, the following instruction, fetched during the current
instruction execution, is discarded and a dummy cycle is replaced to get the proper instruc-
tion (2 cycles). Otherwise proceed with the next instruction (1 cycle).
Skip if [m].i=0
Move the ROM code (current page) to TBLH and data memory
