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 (locate by TBLP and TBHP) to TBLH and data memory (ROM code
TBHP is enabled)
The low byte of ROM code addressed by the table pointers (TBLPand TBHP) is moved to
the specified data memory and the high byte transferred to TBLH directly.
[m]
TBLH
Move the ROM code (current page) to TBLH and data memory (ROM code TBHP is
disabled)
The low byte of ROM code (current page) addressed by the table pointer (TBLP) is moved
to the specified data memory and the high byte transferred to TBLH directly.
