(1) Signals names with (RD) denote the reset default pin name.
(2) Signal Types: I = Input, O = Output, I/O = Input or Output.
(3) Buffer Types: LVCMOS, Analog, or Power (see Table 4-3 for details)
(4) To determine the pin mux encodings for each pin, see the Port I/O Diagrams section.
(5) Sz = The LCD segment that is assigned to each pin can vary by package – see the "LCD SEG" columns for the assignment on this pin.
(6) Reset States:
OFF = High impedance with Schmitt-trigger inputs and pullup or pulldown (if available) disabled
N/A = Not applicable
