I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal, BH = Bus Holder
Input pins of type I, I/O, and I/O/Z are required to be driven at all times. To achieve the lowest power, these pins must not be allowed to
float. When they are configured as input or high-impedance state, and not driven to a known state, they may cause an excessive IO-
supply current. Prevent this current by externally terminating it or enabling IPD/IPU, if applicable.
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 3.8.1 , Pullup/Pulldown Resistors .
Specifies the operating I/O supply voltage for each signal
