Loads a register with value. 

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em ga}]gaem\-Handle for AEM \item[{\em garc\-Addr}]GARC address \item[{\em reg}]register of GARC to load \item[{\em value}]16-bit value to load into GARC register \end{description}
\end{Desc}

\label{gGARC_8h_a2}


Reads a register returing value in {\em val\/}. 

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em ga}]gaem\-Handle for TEM \item[{\em garc\-Addr}]GARC address \item[{\em reg}]register of GARC to read \item[{\em val}]pointer to storage to hold the response of the read command \end{description}
\end{Desc}
\begin{Desc}
\item[Returns:]G\_\-OK on success\end{Desc}
Reads the GARC register specified by {\em reg\/}. {\em val\/} is filled on return.

The following error codes are returned when LATp errors occur:

\begin{itemize}
\item GERR\_\-LATP\_\-HEADER\_\-PARITY \item GERR\_\-LATP\_\-CELL\_\-PARITY \item GERR\_\-LATP\_\-TRUNCATE \end{itemize}
