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 battery can be added in order to
increase the RTC autonomy during power off of the main battery
(power supply). NO Devices must be powered from this pin.
