(1) See technical reference manual (listed in Section 8.3) for more details.
(2) Do not supply external circuitry from this pin.
(3) If internal DC-DC is not used, this pin is supplied internally from the main LDO.
(4) If internal DC-DC is not used, this pin must be connected to VDDR for supply from the main LDO.
