\begin{itemize}
- \item One FN outputs to Many Pins: no problem\\
+ \item One FN output to Many Pins: no problem\\
(weird configuration by end-user, but no damage to ASIC)
\item One Pin to Many FN inputs: no problem\\
(weird configuration by end-user, but no damage to ASIC)
- \item Many Pins to One FN input: {\bf Priority Mux needed}\\
- No priority mux: Pin1 = HI, Pin0 = LO, ASIC is damaged
\item Many FN outputs simultaneously to one Pin: {\bf does not occur}\\
(not desirable and not possible, as part of the pinmux design)
+ \item Many Pins to One FN input: {\bf Priority Mux needed}\\
+ No priority mux: Pin1=HI, Pin0=LO and ASIC is destroyed
\item Some FNs (I2C\_SDA, SD\_D0..3) are I/O Buses\\
Bi-directional control of the Pin must be handed to the
FN
