3.6.1 LDO/VREG

F28003x supports internal and external VREG selectable using the VREGENZ pin. However, not all packages support the external VREG option. For packages that do not support external VREG, the VREGENZ pin is replaced by GPIO39 on the F28003x device. For more details, see the device-specific data manual. F28002x supports only internal VREG and has no VREGENZ pin.
