3.6.1 LDO/VREG

Both F280015x and F28P55x supports internal and external VREG for the 1.2V supply selectable using the VREGENZ pin. However, only the F280013xV supports the external VREG option and has a VREGENZ pin. All other F280013x devices replaced this with a GPIO. For F28P55x all packages have a VREGENZ pin.
