In table~\ref{tab:flags} the flags that can suffix instructions are described. If and which flags are available depends on the instruction. \begin{longtable}{|c|c|c|}\hline \textbf{flag} & \textbf{function} & \textbf{default value} \\ \hline C & carry & 0 (not set) \\ \hline D & Status register update disable & 0 (not 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 +/- & branch taken or not taken & + (set) \\ \hline A & if set the shift operation will be arithmetic instead of logic & 0 (logic) \\ \hline \caption{ISA flag overview} \label{tab:flags} \end{longtable}
