(1) I = input, O = output, P = power
(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) TI recommends shorting unused analog input pairs and connecting them to analog ground.
(4) The pins VDSYS and DVSYS must be connected externally on the board for proper device operation.
(5) When this pin is configured as reset, the internal pullup resistor is enabled by default.
