CC430 Hardware Question (Separate VCC)

Hello All

I chose the CC430F6137 for a low power application.

for more info: CC430  = (MSP430 + CC1101)

at the moment i want to separate the battery used for general MCU application and RF application in my hardware.

as you see in the datasheet these pins are dedicated for RF VCC (Pins: 43 - 42 - 39 - 38)

is it possible to separate the supply voltage for RF Core  (RF applications) and other digital and analog applications ??

thank you in advance
