Instruction Set Architecture—IP2022 User’s Manual 156 www.ubicom.com INCSZ W,fr Increment fr into W then Skip if Zero Operation: W = fr + 1; if result is 0, then skip next instruction Bits affected: None Opcode: 0011 110f ffff ffff Description: This   instruction   increments   the   value   in   the
specified  data  memory  location  and  moves  the
result  to  W.  The  data  memory  location  is  left
unchanged. If  the  result  is  zero,  the  next  instruction  in  the
program is skipped. Otherwise,                                                                                    program
execution    proceeds    normally    with    the    next
instruction. Cycles: 1 if tested condition is false; 2 if tested condition
is true Example: incsz w,0x099;load 0x099 + 1 to W
ret    ;return if 0x099 + 1 is 0
nop    ;otherwise continue here This example takes the contents of data memory
location 0x099, increments that value, and moves
the  result  to  W.  If  the  result  is  zero,  the  ret
