BF707: VDD_HADC and VDD_RTC on battery powered devices

Hi all, we are designin a device using BF707 that will run on battery, so we need to squeeze the maximum out of it.

 

We are not planning to use HADC or RTC, so I was wondering if it is possible to connect VDD_HADC and VDD_RTC to GND. In the data sheet, "Operating Conditions" at page 49, I see no notes on these so I am interpreting that as "these power rails may be left turned off if you don't need them".

 

Could you please tell me if I am right or wrong?

 

Thank you very much

Ilario
