- In/out:
+ In/out: {\bf Note: these all require multiplexing }
  \begin{itemize}
    \item Output-Enable (aka Input disable): switches pad to In or Out
    \item Output (actually an input wire controlling pin's level, HI/LO)
    \item Input (actually an output wire set based on pin's driven level)
  \end{itemize}
- Characteristics:
+ Characteristics: {\bf Note: these do not require multiplexing }
  \begin{itemize}
    \item Output current level: 10mA / 20mA / 30mA / 40mA
    \item Input hysteresis: low / middle / high. Stops signal noise
