IP2022 Data Sheet www.ubicom.com 43 4.5 Key to Abbreviations and Symbols 4.6 Instruction Set Summary Tables Table 4-2    through    Table 4-7    list    all    of    the    IP2022
instructions, organized by category. For each instruction,
the table shows the instruction mnemonic (as written in
assembly   language),   a   brief   description   of   what   the
instruction does, the number of instruction cycles required
for  execution,  the  binary  opcode,  and  the  flags  in  the
STATUS register affected by the instruction. Although  the  number  of  clock  cycles  for  execution  is
typically 1, for the skip instructions the exact number of
cycles  depends  whether  the  skip  is taken or  not taken.
Taking the skip adds 1 cycle. The effect of extended skip
instructions (i.e. a skip followed by a loadh, loadl, or page instruction) is not shown. For  detailed  information  on  each  instruction,  see  the
