1.2V digital core voltage output (internal 1.2V LDO power supply output), this
1.2V output ball provides power to all VDDC/VDDA balls.
Note: Internally generated power voltage. Do not connect an external power
supply to this ball. This ball is used for connecting external filter (Ferrite bead
and capacitors). It is recommended this ball should be connected to 3.3V power
rail by a 100 ohm resistor for the internal LDO application.
