I/O
Input/output port of third most positive analog LCD voltage (V3 or V4)
(1) I = input, O = output
(2) It is recommended to short unused analog input pairs and connect them to analog ground.
(3) The pins VDSYS and DVSYS must be connected externally on board for proper device operation.
(4) VCORE is for internal use only. No external current loading is possible. VCORE should only be connected to the recommended
capacitor value, CVCORE
