Management Data IO
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external
pullup/pulldown resistors are required, see Section 4.8.1, Pullup/Pulldown Resistors.
(3) Specifies the operating I/O supply voltage for each signal
