(1) Signals names with (RD) denote the reset default pin name.
(2) To determine the pin mux encodings for each pin, see Section 9.11.
(3) Signal types: I = input, O = output, I/O = input or output
(4) Buffer types: LVCMOS, Analog, or Power (see Table 7-3)
(5) The power source shown in this table is the I/O power source, which may differ from the module power source.
(6) Reset States:
OFF = High impedance with Schmitt trigger and pullup or pulldown (if available) disabled
PU = Pullup is enabled
PD = Pulldown is enabled
N/A = Not applicable
(7) DNC = do not connect
