11.10 RTC Bypass out
The VRTC pin brings out the Real Time Clock supply, which is separate from the rest of
the digital part, allowing having only RTC going on when all the other parts of the device
are off.
To this power output a backup capacitor can be added in order to increase the RTC
autonomy during power off of the battery. NO Devices must be powered from this pin.
