+In table~\ref{tab:flags} the flags that can suffix instructions are described. If and which flags are available depends on the instruction.

-               C    & carry    & 0 (not set)   \\ \hline
-               SU   & Status register update & 1 (set) \\ \hline
-               H/L  & use high or low 16-bits & L (not set) \\ \hline
-               F    & fill unused 16-bits with value of F & 0 (not set)\footnote{this means that andxf must be used if the not specified 16-bit should be preserve} \\ \hline

-               S    & sign extension & 0 (not set) \\ \hline
