(1) I = input, O = output
(2) VCORE is for internal use only. No external current loading is possible. VCORE should only be connected to the recommended capacitor value, CVCORE.
(3) Before enabling the analog function (A3), pull this pin low by setting the port function to output low or to input with the internal pulldown resistor enabled.
(4) When this pin is configured as reset, the internal pullup resistor is enabled by default.
(5) TI recommends shorting unused analog input pairs and connecting them to analog ground.
(6) The pins VDSYS1 and VDSYS2 must be connected externally on board for proper device operation.
