(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal, MM = Multi Muxed, DSIS =
De-selected Input State
(2) IPD = Internal Pulldown Active, IPU = Internal Pullup Active, DIS = Internal Pull Disabled. This represents the default state of the
Internal Pull after Reset. For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown
resistors are required, see , Pullup/Pulldown Resistors and , Pin Behaviors at Reset.
(3) Specifies the operating I/O supply voltage for each signal
