\item[Parameters:]
\begin{description}
\item[{\em gdab}]gdab\-Handle containing the COM I/O (gnat) handle \item[{\em pdu\-Addr}]PDU address of command \item[{\em reg}]register of PDUC to load \item[{\em val}]ptr to value to write to the register \end{description}

\begin{Desc}
\item[Returns:]G\_\-OK on success\end{Desc}
Loads a register from the PDU Environment Monitoring block specified by {\em reg\/} with {\em val\/} Included only for debugging and should not be propogated through to the LATTE interface \hypertarget{gPDUE_8c_a0}{

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

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em gdab}]gdab\-Handle containing the COM I/O (gnat) handle \item[{\em pdu\-Addr}]PDU address of command \item[{\em reg}]register 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 register {\em reg\/} from the PDU Environment Monitoring block {\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}
