(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
(2) Specifies the operating I/O supply voltage for each signal. See Section 5.3 , Power Supplies for more detail.
(3) PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 kΩ resistor should be used.)
