\begin{itemize}
\item \code{write[bwlq]} ensures all prior writes have been posted
- \item \code{read[bwlq]} ensures read reception before continuing
+ \item \code{read[bwlq]} ensures the read has been issued before continuing
\item Reordering is prevented to avoid trouble if the device expects
one register to be read/written before another one!
\item Sometimes compiler/CPU reordering is not an issue, in this case
