(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 Section 4.5.1, Pullup/Pulldown Resistors and Section 7.3.17, Pin Behaviors at Reset.

(3)

Specifies the operating I/O supply voltage for each signal
