(1)

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

(2)

PULL: A / B, where:

A is the state of the internal pull resistor during POR reset

B is the state of the internal pull resistor after POR and Warm reset are de-asserted and during Warm reset

IPD = Internal Pulldown Enabled, IPU = Internal Pullup Enabled, DIS = Internal Pull Disabled

DRIVE: A / B, where;

A is the driving state of the pin during POR reset

B is the driving state of the pin after POR and Warm reset are de-asserted and during Warm reset

H = Driving High, L = Driving Low, Z = 3-State

For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown resistors are required, see

Section 4.2.1, Pullup/Pulldown Resistors.

(3)

Specifies the operating I/O supply voltage for each signal.
