KEY:
I = Input
TI = Tri-level
O = Output
P = Power supply connection
(T)I/O = Input on power up, becomes an Output after 10 ms
Weak internal pull-up resistors are present on SEL24, EPCI#, FS, LE#, PCISTP#, and SLOW#. These pins should
be tied to VDD or GND, and not be left floating. Internal resistors on PEN, SEL AUDIO, and TS pull to mid-level (M).
