(1)

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal

(2)

IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external

pullup/pulldown resistors are required, see Section 3.9.1 , Pullup/Pulldown Resistors.

(3)

Specifies the operating I/O supply voltage for each signal
