+\frame{\frametitle{Why, How and What is a Pinmux?}
+
+ \begin{itemize}
+   \item Why? To save cost, increase yield, and to target multiple
+         markets with the same design, thereby increasing uptake
+         and consequently taking advantage of volume pricing.\vspace{10pt}
+         \\
+         Summary: it's all about making more money!\vspace{10pt}
+   \item How? By multiplexing many more functions (100 to 1,200) than there
+         are actual available pins (48 to 500), the required chip package
+            is far less costly and the chip more desirable\vspace{10pt}
+   \item What? A many-to-many dynamically-configureable router of
+         I/O functions to I/O pins\vspace{10pt}
+  \end{itemize}
